Description Jaime Velasco Juan 2008-01-09 09:58:47 UTC

The decorations of the windows and buttons drawn by icewm are broken. The corruption changes when moving the mouse over the buttons, and seems related to other parts of the screen.

I tried bisecting the issue and it is present at least since commit 2e2e95 (Jun 24 2007). I could try some older version if needed, but I'd need to downgrade the kernel and recompile everything.

Also tried options "shadowfb" and "noaccel", but the server gets killed with signal 11 when it starts.

I'll attach logs and one screenshot showing the problem

Comment 4 Maarten Maathuis 2008-01-09 10:21:45 UTC

Only IceWM has this problem?

Does it also occur when randr12 is disabled?

Comment 5 Jaime Velasco Juan 2008-01-09 10:40:45 UTC

Yes, it only happens with icewm (well, I've never seen it with anything else) and yes, it happens with and without RandR12

Comment 6 Maarten Maathuis 2008-02-01 13:25:27 UTC

Perhaps we should first debug why NoAccel causes a crash, please submit a xlog of that.

Fix NoAccel (and ShadowFB)

I bisected the NoAccel issue, the problem was introduced with

commit 2af4a28ae1df46686e264bcda417a896b7cfa59a

    Hook up DMA funcs to channels/grobjs etc etc

With this patch, NoAccel works again.
Regarding the original bug with iceWM, I'm not able to test/do anything now, but hopefully will be the next week.

Regards

Comment 8 Maarten Maathuis 2008-02-03 06:48:12 UTC

I pushed that patch. I'll keep an eye on this bugreport.

Comment 9 Jaime Velasco Juan 2008-02-08 10:47:59 UTC

I finally got to testing this again after reinstalling my OS and now I can't reproduce it. I've tried downgrading the xserver and using an old nouveau version, but it works fine now.

I don't know where could be the problem, so I'll close the bug with WORKSFORSOME,
sorry for the noise.
