Description

Desktop effects enabled? Which graphics card? I have a Radeon 9800 Pro video card which is identified as R350 NH in Xorg.0.log. No desktop effects, just plain boot from the Live CD. regards Huub Is this the same like https://bugzilla.novell.com/show_bug.cgi?id=361467 ? It certainly seems to be. 361467 describes what I see quite nicely and the QT_USE_NATIVE_WINDOWS setting works for me as well, so I assume it's the same issue. *** Bug 157887 has been marked as a duplicate of this bug. *** *** Bug 158546 has been marked as a duplicate of this bug. *** *** Bug 160081 has been marked as a duplicate of this bug. *** People might be more likely to notice this as the original bug if the description was better :-). I'm seeing pretty much the same behaviour (trunk/r752596). I'm using an NVIDIA 8600 GTS using the non-free driver (169.12). The problem appears using both OpenGL and XRENDER for desktop effects. The drawing errors are also available for any of the window decorations I tried (Oxygen/Plastik/Keramik). I tried using QT_USE_NATIVE_WINDOWS as stated above and it seems to make things a little better however that's just a subjective feeling I have. Created attachment 24157 [details]
Drawing errors on resizing windows in kwin
Just for the reference I'm attaching 2 screenshots I made. One after
horizontally shrinking the window, the other after horizontally enlarging the
window.

I see the same drawing errors regardless of wether I:
- disable effects in the Desktop settings
- disable Composite and XRENDER in my xorg.conf
In any case the border and icons get redrawn correctly when they get refreshed (eg. on clicking outside the window).
I just compiled r793556. Either this or Qt4.4rc1 seems to have fixed it. Same here. Lubos, please close this (I'd do it, but I'm not sure if you would prefer WORKSFORME or FIXED; you probably know better if Qt was the problem...). Not fixed yet.
