This is how it looks.
Please report this issue to the bug tracker of your distribution. They can decide if the bug is with the X server or the video drivers. Created attachment 89353 [details] attachment-12269-0.html Ok, sorry i have no distribution bug tracker because I built one from the `Linux from Scratch' book and now it became quite different from the book's distribution, but i did suspect the X server had something to do, i will try to rebuild the X server upgrade or downgrade it, since most likely the video drivers have nothing to do. Thank you for your response, once I find out what is going on I will write again to inform you. Thank you again. 2014-10-28 17:45 GMT-04:30 Christoph Feck <christoph@maxiom.de>: > https://bugs.kde.org/show_bug.cgi?id=340432 > > Christoph Feck <christoph@maxiom.de> changed: > > What |Removed |Added > > ---------------------------------------------------------------------------- > Resolution|--- |DOWNSTREAM > Status|UNCONFIRMED |RESOLVED > CC| |christoph@maxiom.de > > --- Comment #2 from Christoph Feck <christoph@maxiom.de> --- > Please report this issue to the bug tracker of your distribution.

Hello, it turns out that it seems to be a KDE bug, related to pixmap
caching.
if I do this
rm /var/tmp/kdecache-<username>/icon-cache.kcache
all icons are ok, and amarok thing, is because it uses a background pixmap
in the play list wich I assume is also cached to the filesystem. In fact
there is an Amarok-pixmaps.kcache file in /var/tmp/kdecache-<username> a
deleted it but the problem persists though it goes away for a moment.
If you think this is not a BUG please let me know.
Thanks in advance.
I have no idea how the pixmap caches work; I had the impression they are converted to QImage and stored as raw image data. It could be a bug in the cache, or a bug in the drivers that are responsible for converting the X11 pixmaps to Xrender images. Keeping this open, but do not expect anyone to have an idea, until someone knows how to debug it on your system. There is no KDE bug. I am developing an application that uses a Zebra label printer which stores image data in PCX format, i have a custom image format plugin for Qt which handles PCX but not all possible `QImage::Format formats' only 1BPP monochrome and a few color formats `don't remeber which ones right now' and it was conflicting with KDE's implementation of PCX format since it was in the main Qt plugins directory, i found out that the cache data is saved as PCX and converted to PNG before rendering and that was the cause of the problem. I am very sorry for this, I had to investigate it before sending this report, but I had no time, so I ended up wasting your time instead of mine. I appologize again, sorry and thank you very much for your support. And sorry if I have spelling errors, english is not my native language it is spanish. Thanks for the update, let's close this then. |
