Created attachment 52138 [details]
Example of miniature of the konsole window!

Version:           4.5 (using KDE 4.5.1) 
OS:                Linux

In KDE 4.5.1 there is no miniatures at all (in the edge of the window on Ctrl+Meta+T and task panel), instead of them there is a white squares (see attachment).

Reproducible: Didn't try

have a look at the dupe, identify your gl renderer/version string, append it to the blackist in kwinrc and attach the glxinfo snippet to the (other, not this) bug as well, thanks.

Comment 2 msnkipa 2010-10-01 18:01:27 UTC
How can I find out this "gl renderer/version string"?
Comment 3 msnkipa 2010-10-01 18:10:38 UTC
I also want to add that I can solve this problem by switch to the "bilinear" and "memory safe" options in the desktop effect`s configuration dialog.

PS: on the previous KDE version 4.4 anything work prefect!
Comment 4 Thomas Lübking 2010-10-01 18:45:40 UTC
echo "`glxinfo | grep 'OpenGL renderer string' | sed -e 's/^.*: //'`:-:`glxinfo | grep 'OpenGL version string' | sed -e 's/^.*: //'`"

4.4 didn't have the lanczos filter, which is a visual improvement but requires working shaders (what you GPU/driver does not provide) and a "not too weak" GPU
Comment 5 msnkipa 2010-10-04 09:02:40 UTC
I have
Mesa DRI Intel(R) 965GM GEM 20090712 2009Q2 RC3
2.1 Mesa 7.6
How must line in the blacjlist in the kwinrc look like?
Comment 6 Thomas Lübking 2010-10-04 17:28:36 UTC
[Blacklist][Lanczos]
Intel=$DRIVERSTRING

where "$DRIVERSTRING" is the output of the bash script in comment #4
echo "`glxinfo | grep 'OpenGL renderer string' | sed -e 's/^.*: //'`:-:`glxinfo
| grep 'OpenGL version string' | sed -e 's/^.*: //'`"

please do not again change the bug resolution as duplicate, thanks.
