Created attachment 327875 [details] Crumpled Firefox window title User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.4) Gecko/20091016 SUSE/3.5.4-1.1.2 Firefox/3.5.4 This bug is the special case of the bug from KDE bug tracker (https://bugs.kde.org/show_bug.cgi?id=199735). Its status there is "RESOLVED", but I still experience the problem. Reproducible: Sometimes Steps to Reproduce: 1. Let the OpenGL compositing is allowed. 2. Let some window to change its title (for example, switch tab in Firefox) Actual Results: Title redrawing fails and it becomes "crumpled". Expected Results: Title should be redrawn properly, without any artifacts.
I am experiencing similar drawing issues where a corner of a window is not redrawn properly. It occurs occasionally and is very difficult to reproduce. When it occurs it is annoying and, most importantly, gives an immature impression. This is a new problem in KDE4 and wasn't there in previous versions. I am also using OpenGL extensions.
