Running MSEide with -ns option (No skin)
Using Debian stable, testing, sid, Ubuntu 12.04.... Really this happens since KMS was used IIRC. In fact using radeon.modeset=0 fixes it for some ATI cards MSEgui renders dirty regions first on a pixmap which will be copied to screen by xcopyarea() after completed rendering. It seems the problems with current radeon driver are independent if there are stretched xrender pictures or not. Created attachment 86142 [details]

Test program
Attached test program. Press Alt+ArrowDown,Esc. The project is here: https://gitorious.org/mseuniverse/mseuniverse/source/54e47cd378d8ef208df0dbbf69302e9ef85216ca:testcase/graphics/radeon The same issue using nouveau driver can be solved disabling acceleration.
For example:
Section "Device"
Identifier "Nouveau"
Driver "nouveau"
Option "NoAccel" "on"
EndSection
Using radeon, only EXAPixmaps off is required.
Disabling radeon's EXAPixmaps also mostly disables hardware acceleration. Intel driver is not affected because doesn't use EXA. IIRC using XAA instead of EXA is working fine too so all is pointing to EXA. Created attachment 97945 [details]

Test not OK
We could simplify the testcase: https://gitorious.org/mseuniverse/mseuniverse/source/testcase/graphics/radeon Running the program in debugger and moving the window shows an image like the attachment "Test not OK". MSEgui draws the button glyph by a xfillrectangle() with the glyph bitmap as stipple mask. It seems that if there follows an immediate xdrawlines() which touches the xfillrectangle() area the distortion happens. Example: xdrawlines() with ((x:24;y:25),(x:130;y:25),(x:130;y:50)) -> distorted, xdrawlines() with ((x:24;y:25),(x:80;y:25),(x:80;y:50)) -> OK. Also "xflush(); sleep(10ms);" or "xsync()" between xfillrectangle() and xdrawlines() prevents the distortion. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
