Summary: Graphical corruption when opening windows Product: DRI Version: XOrg CVS Platform: x86-64 (AMD64) OS/Version: All Status: NEW Severity: normal Priority: medium Component: General AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: h.judt@gmx.at

Created an attachment (id=43507) --> (https://bugs.freedesktop.org/attachment.cgi?id=43507) screenshot of the garbled frame

Although it is visible only for a very short moment, I was able to capture it, see the screenshot attached to this bug. It seems something doesn't get initialized correctly like it used to before, part of the garbled area looks like it's previous screen content, just pretty messed.

* I think this only happens when using compositing, but did not test it, so I'm not sure. * Is noticable with xfwm4 (the xfce window manager) and compiz. * Is only noticable sometimes (maybe because the other times it's just too fast, but I'll try to capture it with recordmydesktop). * It can be seen on various window types, like the small firefox / thunderbird frame which appears before the normal window appears, or menus. * It is not constrained to window size. * This did not happen some time ago, but I don't know when it started. Before it started, the windows were simply grey.

Software and versions: * git vanilla kernel (2.6.38-rc5), certainly happened with 2.6.37 * git mesa (r600g) * git xf86-video-ati * git libdrm

--- Comment #1 from Harald Judt h.judt@gmx.at 2011-02-18 00:39:56 PST --- Update:

* It seems this is not related to mesa vs gallium, as it both happens when using r600c or r600g. * If I turn off Option "Composite" (set it to "Disabled"), then the corruption does not appear.

I've found this similar bug, https://bugs.freedesktop.org/show_bug.cgi?id=27529, but there the issue is more severe.

--- Comment #3 from Harald Judt h.judt@gmx.at 2011-02-21 01:43:42 PST --- No, Option "ColorTiling" is not in xorg.conf. I've added it now, but setting it to true or false makes no difference at all.

Option "AccelMethod" "EXA" Option "EnablePageFlip" "on" Option "ColorTiling" "true" Option "ClockGating" "1" Option "DynamicPM" "on"

I'd say it can't be page flipping either because the problems started quite some time before it was introduced.

...

Any chance you could track down which component is problematic (drm, ddx, or mesa) and bisect?

Chance yes, but bisecting will be /very/ time-consuming as it needs compiling different kernel versions, mesa, etc. Some of these packages will only compile with specific versions of other packages.

Can't we exclude some packages from the beginning? How about mesa, is it used for compositing without opengl windows manager? I've already switched between gallium and classic mesa, and it did not change anything.

--- Comment #10 from Michel Dänzer michel@daenzer.net 2011-02-23 08:38:46 PST --- I guess it's most likely an xserver issue. E.g. commit 6dd775f57d2f94f0ddaee324aeec33b9b66ed5bc ('composite: Don't backfill non-bg-None windows') looks possibly relevant.

Sounds like bug 27596 btw (though AFAICT that was reported before the change above was made).

--- Comment #11 from Harald Judt h.judt@gmx.at 2011-02-25 01:43:48 PST --- Thanks for pointing me to this. The symptoms looks indeed very similar, though I do not start X server with option -wm:

xinit /etc/X11/xinit/xinitrc -- /usr/bin/X -dpi 96 -auth /home/xxxxx/.serverauth.13388

Hopefully I will find some time next week to check this out.

Patch which reverts commit 6dd775f57d2f94f0ddaee324aeec33b9b66ed5bc

I have rebuilt the Fedora 15 RPM with the attached patch (which reverts commit 6dd775f57d2f94f0ddaee324aeec33b9b66ed5bc), and the problem appears to be mostly gone.

I no longer see any corruption when opening menus and most windows. I did see a bit of corruption when opening up Thunderbird just now, but I'm willing to put that down to KDE's "Glide" effect.

Thanks for confirming that. However, I'm not sure this is really a bug in the X server, or possibly rather in the clients. Adam?
