compiz causes crash with fullscreen sdl applications (gutsy)

[ChrisC]

Binary package hint: compiz

SDL_WM_ToggleFullScreen( surface );

execute this to kill xwindows!

As this is in a lot of games this directly effects bug #1 !
(I feel this is an important issue that needs resolving before release
as this will put off games players trying out Linux for the first time)

http://nehe.gamedev.net/data/lessons/linuxsdl/lesson11.tar.gz
see this code for a good example (NB mouse must be over window to see activity)

also notice pause of about half a second every second when compiz is used

Workround: disable compiz, apps work fine

Thank you for taking the time to report this bug and helping to make Ubuntu better. Can you please provide the version information for your compiz installation. In addition was this version of compiz from the Ubuntu repository, or downloaded elsewhere?

Thanks,
Justin M. Wray

as per title its gutsy

I can confirm its compiz from the Ubuntu repository

[ChrisC (chris-chris-camacho-deactivatedaccount)]

since todays update fullscreen toggle doesnt cause crash

However with compiz enabled still a pause for a second every few seconds
this doesnt happen with compiz disabled

[Justin M. Wray (wray-justin)]

Added upstream bug as well, http://bugs.opencompositing.org/show_bug.cgi?id=305

Thanks,

seems to me compiz doesnt play nicely with direct rendering

There needs to be some kind of standard ?xlib? method to arbitrate
opengl direct rendering

[Travis Watkins (amaranth)]

That is not the upstream compiz bug tracker.

[ChrisC (chris-chris-camacho-deactivatedaccount)]

So why not suggest the correct one?

[Justin M. Wray (wray-justin)]

Launchpad is listing it as the bug tracker. And they do appear to track bugs on http://www.opencompositing.org/ as well, according to the site.
Do you know the correct upstream tracker? The main compiz site does list, bugs.freedesktop.org, as a tracker.

Any ideas?

Thanks,
Justin M. Wray

[Travis Watkins (amaranth)]

The freedesktop one is the correct place for compiz bugs. The opencompositing one is for compiz-fusion bugs. They have a core option in their bug tracker for people that incorrectly file core bugs on their bug tracker.

[Justin M. Wray (wray-justin)]

I will refile on freedesktop. Any reason Launchpad is listing the compiz-fusion tracker?

Thanks,
Justin M. Wray

At least I found a possible source of this problem (not only for sdl apps), see https://bugs.launchpad.net/bugs/138424

I have to reset one Compiz plugin to make things work again.

in short, this is what I observe (copy from 138424 ...)

The strange behavior for apps. launched on fullscreen (Nautilus or other applications) was caused(on my machine) by a Compiz plugin named PLACE WINDOWS under WINDOWS MANAGEMENT SECTION.

This plugin has 4 possible states = 4 possible ways to put a window on desktop when this window is generated.

1 Centered
2 Smart
3 Maximize
4 Random

The subject of this bug report is this RANDOM mode.
When RANDOM mode is activated - this plugin try to calculate a random X and Y start points for the new generated window.
This is in oposition with the case when a window try to start in fullscreen mode and X,Y = 0.

Changing this mode to CENTERED mode solve my problem.
