blender ui garbled

[Ingo Planz]

Binary package hint: blender

In feisty the blender ui is not drawn correctly: that is, neither the widgets nor the the text appear. Sometimes they do redraw -- so moving the mouse and clicking somewhere occasionally shows some widgets. But in general the ui is unusable. The 3D view is also garbled.

This happens with both desktop effects enabled and disabled.

Feisty i386 on an Thinkpad T41, that is a Radeon Mobility 7500 using the X.org RADEON driver.

[Ingo Planz (planz)]

The bug persists in blender-2.44 from blender.org (python-2.5). The static MesaGL version is fine though. (Almost actually: With desktop effects enabled, it is semi-transparent...)

glxinfo says

OpenGL vendor string: Tungsten Graphics, Inc.
OpenGL renderer string: Mesa DRI Radeon 20061018 AGP 1x x86/MMX/SSE2 TCL
OpenGL version string: 1.3 Mesa 6.5.2

i also have this bug and have the same video card Radeon Mobility 7500 on a dell inspiron5100

[KIAaze (zohn-joidberg)]

Same problem here:
ATI IGP 345M video card with 64MB shared memory
Compaq presario 2500
Ubuntu Gutsy Gibbon

glxinfo:
OpenGL vendor string: Tungsten Graphics, Inc.
OpenGL renderer string: Mesa DRI Radeon 20061018 AGP 4x x86/MMX/SSE2 NO-TCL
OpenGL version string: 1.3 Mesa 7.0

i am on feisty fawn

The similar problem here.

Ubuntu 7.04 , Intel display card

with Desktop Effect enable.

OpenGL games like Tremodous works fine.

[Garritzman (dongarritz)]

Same problem on Feisty... error string from Terminal:

:~$ blender

Compiz Fusion installed and working fine.

Confirmed.Feisty on IBM Thinkpad T42, ATI Radeon 7500. All other OpenGL software works perfectly. This bug makes blender unusable.

[KIAaze (zohn-joidberg)]

Just to link to this thread from the Ubuntu forums:
http://ubuntuforums.org/showthread.php?t=436693&highlight=Blender

I would also like to add that Blender works correctly in Windows XP, but not in Ubuntu on the same PC.

[KIAaze (zohn-joidberg)]

This bug is largely confirmed I believe. And I believe it's critical.

[Ingo Planz (planz)]

On Gutsy Beta, this bug is (mostly) fixed for me: 3d view is fine, widgets are only occasionally missing. However it crashes quite frequently now (bug #148037).

[Vadim Peretokin (vperetokin)]

On Gutsy, Radeon 7500, Blender completely locks up my T40 now.

[Treefrogman (treefrogman)]

I too had this problem with Blender 2.46 on Hardy. As per some comments on:
http://ubuntuforums.org/archive/index.php/t-436693.html
I tried turning off Desktop Effects (System>Preferences>Appearance>Visual Effects>None) and this cleared it up perfectly.

[KIAaze (zohn-joidberg)]

Well, it has been working for me for some time now.
I don't even know exactly since when, but it works in windowed and
fullscreen mode now.
I do have desktop effects turned off, but I always had them turned off, so I
don't think it's the only reason.

[5][~]$ blender --version
guessing 'blender-bin' == '/usr/bin/blender-bin'
Blender 2.45 (sub 0) Build

It's strange, I'm running Intrepid and have v2.45 instead of v2.46... ^^

Please try one of the "Static MesaGL version" from http://www.blender.org/download/get-blender/

This will help us know if this is a OpenGL driver bug.

[Vadim Peretokin (vperetokin)]

I have upgraded my laptop since then to one with an nVidia 8600GT card and Blender is working fine on it. But as Ingo also pointed out, the static version probably works fine.

[dreckkopf (dreckkopf)]

I upgraded my system to Hardy with improved ATI drivers. Now everything works fine. I think the problem didn't exist with the static version, but there was some other problem (speed? crashes? I don't remember.) which made the static version unusable as well.

"Please try one of the "Static MesaGL version" from http://www.blender.org/download/get-blender/

I used blender-2.48a-linux-glibc236-py25-i386-static.tar.bz2 downloaded from the given link and tested with and without fullscreen (./blender and ./blender -W).
Both worked without problems (except that it's a bit slow to draw the "about" screen, when joining areas or when resizing an area).

As for the blender installed from the Ubuntu repositories (Blender 2.46 (sub 0) Build), it works without problems too (and no slowliness) on Ubuntu Intrepid 8.10. :)

[Sandro Giessl (sgiessl)]

I had the problem of a garbled blender GUI as well:
- switching the active windows sometimes resulted in the contents of the blender window sticking at the top, hiding all other windows
- after switching back to blender, some parts of the contents couldn't be redrawn correctly (usually this could be fixed be changing UI modes or hovering all areas of the window with the mouse)

My system: IBM Thinkpad T41 with an ATI Radeon Mobility 7500

Finally I was able to fix the problem for me by turning off the composite extension which is turned on by default:

- /etc/X11/xorg.conf:
Section "Extensions"
  Option "Composite" "Disable"
EndSection

- For what it's worth, this is my device section of /etc/X11/xorg.conf (does not seem to be related to this blender rendering glitch):
Section "Device"
        Identifier "ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500]"
        Driver "ati"
        BusID "PCI:1:0:0"

# fix redraw slowness in jaunty! 20090502
 Option "AccelMethod" "EXA"
 Option "MigrationHeuristic" "greedy"
 Option "AccelDFS" "true"
 Option "EnablePageFlip" "true"
 Option "EnableDepthMoves" "true"
EndSection

By the way, in addition to my previous post I would like to add:
- Ubuntu 9.10 Jaunty
- Blender 2.49a-ubuntu0904-1 (.deb from the official release downloadable from blender.org - the problem did also exist with blender 2.48a+dfsg-1ubuntu3 as shipped with ubuntu and should be resolved there as well)
