Created attachment 52923 [details] screenshot of corrupted icon Version: unspecified (using KDE 4.5.2) OS: Linux Since updating to KDE-4.5 I experience icon corruptions in KDE applications. Some icons look like the icon in the attached screenshot, the corruptions happen in various places like context-menus or even in application-main windows. The screenshot was taken from GwenView main window's zoom bar. I also don't think its an X11/driver issue, because if the icon changes e.g. on mouseover, the new icon is drawn correctly, when I move the mouse away exactly the same corruption appears. It also happens with the VESA driver. I am running KDE-4.5.2 on Fedora-13 with DBus-1.4. Reproducible: Didn't try
Can you check if the problem persists if you delete the icon caches (these are the files kpc/* and *.kcache in /var/tmp/kdecache-<user>)?
Yes that solved the problem, at least for the specific case where I saw the corruption the last time. I'll report back if it occurs again.
Unfourtunatly, after I've deleted the icon cache I've seen the problem again. I've attached a screenshot.
Created attachment 53024 [details] screenshot after icon cache was deleted
so, kde 4.5.2 is buggy on my system - what can I do to track the problem down and help getting it fixed? Does this report have to go the route of the ~40 other open reports I have, beeing ignored because kde developers integrate tons of new, untested and again buggy features.
any help tracking this problem/bug down?
should I make my icon-cache with the corrupted icons available for download?
Just seen again with kde-4.6 and a fresh installation.

Created attachment 60486 [details] Corrupted icon effects I have been having a similar issue with kde-4.6.2 on fedora 14. Sometimes even the mouse cursor is rendered mostly invisible, making it very difficult to use the desktop. I found that clearing the icon cache and rebooting seems to clear things up temporarily, so I modified my bootup scripts to remove the icon caches prior to starting the kdm process as a workaround. Unfortunately, the issue still occurs, although it now seems to be more consistent in its behaviour. Now the icons are displayed correctly, but the mouse-over effects are not. An example has been attached. Additional Note: My graphics card is fairly old (ATI Radeon 9250), so it could potentially be an issue with the hardware/drivers. I don't think it's a hardware issue though, since more than half the time everything displays correctly.
Another note: I was able to get my icon corruption to clear up using the following steps. 1. Change the desktop theme. 2. Remove the theme cache for the desired theme. (In my case ~/.kde/cache-gpaul.dev.linux/plasma_theme_Laughlin.kcache) 3. Change the desktop theme back to the desired. This forced KDE to regenerate the theme cache file and cleared up the corruption.
for me this only helped temporarily, after a few days/weeks more and more icons started to break again.
Do your icons start to get corrupted only after the desktop has been running awhile? My issue seemed to occur during the initial startup phase.
Here icons, menus and plasma become corrupted after a while. I've noticed that opening and scrolling through large PDF files in okular is almost certain to trigger this. My system is opensuse 11.4, KDE 4.6.4, radeon 9550 graphics card. In the beginning I thought it was driver/graphics card related, however I observed this later with remote X server clients and an Intel graphics card.

Seems like graphical corruption related to drivers.
