Version: (using KDE 4.4.0) Compiler: precompiled from http://kde-redhat.sourceforge.net/, repo: kde-testing OS: Linux Installed from: Fedora RPMs Sometimes (rarely) a part of an opened window gets transparent when hovering over a plasma widget (no matter which) ie. in the taskbar. The bug exists at least since KDE 4.1. I made a screenshot of that bug: http://www.bas89.de/screens/Bildschirmfoto51.png The tooltip triggering the bug has closed in the time KSnapshot started. After closing the affected window and opening it again the bug disappears. I’m using an Intel graphics chip without activating any 3D effects. 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03) If you want more information please ask. This is my first bug report.
Created attachment 40879 [details] Example Screenshot. The transparency “hole” is not necessarily under the tooltip, it can be anywhere else on any application window.
This has been reported a couple of times, unfortunately, it is a long-standing X.org issue: bug 177959 / bug 173686. Thanks *** This bug has been marked as a duplicate of bug 177959 ***
Damn. I searched a long time :\ Alright, thanks.
This is clearly a Xorg bug, I was able to write a xlib-only testcas (as I was asked for), but then nothing happend. If you want this bug fixed, please vote for it and make some polite noise at: https://bugs.freedesktop.org/show_bug.cgi?id=22566
