Loss of window border (white flash) when using compiz resize plugin, option=normal

[andbelo]

Binary package hint: compiz

My settings have compiz enabled, the resize plugin enabled with the option mode=0. This option corresponds to "Normal", which is the draw of the window during resizing and not a rectangle. The expected was to have the windows resized without any image artifacts. Currently, the window decoration is lost and a white border is shown (see attachments for examples). This happens with both metacity and emerald window decorators.

I can confirm this bug. I have the exact same behavior on my Intel GM965:

00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
        Subsystem: Lenovo Device 20b5
        Flags: bus master, fast devsel, latency 0, IRQ 28
        Memory at f8000000 (64-bit, non-prefetchable) [size=1M]
        Memory at e0000000 (64-bit, prefetchable) [size=256M]
        I/O ports at 1800 [size=8]
        Capabilities: <access denied>
        Kernel driver in use: i915
        Kernel modules: i915

It seems only to appear on some windows though. For example, Update Manager windows can be resized without any artefacts...

I have slightly different bug, which can be described by the same words "loss of window border when using compiz", and I use Normal option for resize too. At this moment changing of this option gives me nothing. The problem is that all outside the application area of window is _completely_ lost (see attached screenshot). Maximized windows fill all the screen, so that it doesn't even think that there should be some border elements.
Should I file another bug or is it modification of this one?

I use an 8th generation Nvidia videocard.

[Keno Cabazares (kenocabazares)]

i happened to also have the same problem,.. i solved it by checking "loose binding" under compiz options accessed from fusion-icon.

[andbelo (andbelo)]

this sounds interesting, but when I tried to find the "loose binding"
option I couldn't find it. I'm running the compiz installed by default.
Are you using any other installed package or version of compiz?

hmm… my problems gone after removing with aptitude compiz files and e17 files & installing compiz again.

[dreadyman (dreadyman16)]

I tested and with compiz-fusion with "loose-binding" option enabled the problem is solved.

[Jan van de Velde (jmvdvelde)]

Just bought a new videocard wirh Nvidia chipset to replace freaking ATI Radeon. Got same problem no borders, solved by loose binding option. Thanx>!

[Adam Lyall (magicmyth)]

I'm seeing this same issue on multiple Intel IGP chips in different laptops. GMA 950, x3100, and a GMA 4500M. I also have a system with a ATI R300 running Ubuntu Karmic with the 2.6.32 kernel from ppa using KMS and Xorg-updates which does not exhibit this issue so it seems specific to the Intel cards. Not sure if the Nvidia issue is the same as I believe loose-binding was intended to always be used with the Nvidia blob anyway.
I first noticed this issue during Jaunty when I moved to the Linux kernel 2.6.31 (from kernel ppa) on my Sony Vaio CR11s (x3100). Prior to that I had not experience the issue. I'm writing this from a live usb using a daily Lucid release and the same issue is present but appears to affect the new theme even more. I can produce the affect with any window but it is much harder with some apps than others. For example the Update Manager rarely shows the issue unless you go crazy with resizing (grab a corner and throw it around the screen), where as firefox will show it constantly when resizing. It also seems more common with some themes than others. I would say the more complex the apps is (more widgets to cause redrawing) the more easier the bug is to produce.
I can grab some more info from my Sony Vaio if needed (after I have poke through the wikis on how to do this).

[Bálint Magyar (balintm)]

I can confirm this bug on GMA950 on Lucid beta1. Problem does not occur unless the Mode setting of the Resize plugin is on "Normal." Perhaps a bug of gtk-window-decorator?

$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

[andbelo (andbelo)]

It also happens in Lucid beta2

[willjcroz (willjcroz)]

Same problem here: flickering window borders when resizing with resize plugin option=normal. Fixed with loose binding workaround. Thanks.

[willjcroz (willjcroz)]

oops, forgot to say using Lucid Beta2 with radeon (open source) driver

[Adam Lyall (magicmyth)]

I was wrong about it not occurring on my Ati GPU earlier. It just takes more effort and happens more frequently with the new Ambiance theme.
$ lspci | grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R300 ND [Radeon 9700 Pro]

The Sony Vaio Cr Intel GPU
$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

I've upgraded both these systems to Lucid beta 2 and the same issue still persists. Like others, using compiz with --loose-binding fixes the issue. Does anyone know what loose binding really does or more specifically what is the downside to using it as I imagine it would be used by default if there were no issues with it? All I could find out is that "textures are enabled when created" from the Compiz troubleshooting wiki.

[Patrick Pfeifer (patrick2000)]

This must be kernel related as well. Adding "nomodeset" to the kernel command line (press F6 in ubuntu 10.04 boot screen and choose "nomodeset") solves the issue for me.

[Daniel van Vugt (vanvugt)]

Confirmed, this is still a problem in Ubuntu 11.10.

[Daniel van Vugt (vanvugt)]

Sam, do you mean this was fixed by: lp:~smspillaz/compiz-core/compiz-core.fix_930071 ?

If it wasn't that commit then I'm pretty sure this isn't fixed yet, because I was still seeing it in testing 2 days ago.

[Daniel van Vugt (vanvugt)]

Just tested the latest lp:compiz-core (revision 2996) and this bug still occurs when I resize a window rapidly.

[Daniel van Vugt (vanvugt)]

Tracked the colour of the flash down to:
plugins/opengl/src/screen.cpp:GLushort defaultColor[4] = { 0xffff, 0xffff, 0xffff, 0xffff };

Changing that colour changes the colour seen with this bug. So it would seem that when this bug occurs, it means the decor plugin has somehow failed to texture the window decorations and just fills the decorations with the default fill colour.

Indeed, see the "failed to bind pixmap to texture" errors from the
terminal. The fix for this is to use XSync to synchronize between pixmap
updates while resizing, but that could be a rather tricky task. Maybe
keeping a list of pixmaps in gtk-w-d and then having an XSyncAlarm to
notify gtk-w-d when its ok to free a pixmap would be good ?

[Launchpad Janitor (janitor)]

This bug was fixed in the package compiz - 1:0.9.8+bzr3249-0ubuntu1

---------------
compiz (1:0.9.8+bzr3249-0ubuntu1) quantal-proposed; urgency=low

  * New upstream snapshot.
    - Fall back to a refresh rate that is more likely to look correct; 60Hz.
      (LP: #1009338)
    - Benchmark plugin should consume its key binding, and not pass the key to
      the underlying window. (LP: #1009320)
    - Avoid needless STL operations leading to expensive heap operations.
      (LP: #1006335)
    - Fix a typo that was causing (LP: #1002606)
      (widthIncBorders/heightIncBorders)
    - Check if the window is decorated before trying to change its event window
      states (which won't exist if not decorated) (LP: #1007754)
    - Use the XDamage extension more efficiently (the way it was designed to be
      used). This dramatically reduces CPU usage, reduces wakeups, and
      increases frame rates. It also solves at least one observed performance
      bug (LP: #1007299) and probably several more.
    - Avoid constructing and destructing lots of strings on every single event,
      which was wasting lots of CPU (LP: #1005569)
    - md LINGUAS doesn't exist, it's mnk (Mandinka in ISO 639-3)
    - Move grid plugin to google test and don't depend on the plugin for the
      test (LP: #1005009)
    - Don't read plugin.Initialized and test the value. (LP: #1004848)
    - libcompizconfig's install () commands were still using the old includedir
      and libdir variables rather than their libcompizconfig_* variants.
      (LP: #1005176)
    - Execute the cmake files separately to ensure that DESTDIR is respected.
      (LP: #1005177)
    - Don't set_target_properties on a target that might not exist
      (LP: #1005008)
    - Don't allow windows which we weren't even tracking as decoratable to
      become decorated if they try and change their hints. (LP: #963794)
    - Change the mouse pointer while dragging windows in expo. Just like the
      ubuntu branches do. (LP: #987647)
    - Fix uninitialized memory use (LP: #1004338)
    - Fix uninitialized variable (LP: #1004335)
    - Delay unbinding of pixmaps until then next rebind (LP: #729979)
      (LP: #1002602)
    - Don't drop plugins from the list to try and load before you've even tried
      to load them. Doing so makes missing plugins silently ignored instead of
      an error message (LP: #1002715). It also means valid plugins in more
      unusual, but real locations in LD_LIBRARY_PATH will never get loaded
      (LP: #1002721).
    - If running test cases under a real X server, we don't care if Xvfb is
      missing (LP: #994841)
    - Don't assume pkg_check_modules always sets _PREFIX (LP: #993608)
    - Don't clear selections in ~PrivateScreen because it causes a race between
      the existing and the new compiz instances, breaking --replace and
      non-replace behaviour. (LP: #988684) (LP: #989545)
    - Always paint with infiniteRegion as the clip region if the window is
      transformed and always use the supplied region if painting with offset or
      on transformed screen. (LP: #987639)
    - Add synchronization primitives to the decoration protocol so that there
      isn't a r...
