I just upgraded KDE to 4.5 RC1 and some desktop effects (window thumbnails,
present windows) no longer work. In particular, window previews are too
bright. More info here:
It looks like this is due to the introduction of the Lanczos filter in kwin,
which is apparently not well supported by the intel graphics stack. I hit this
bug both on my laptop (with GM965) and my desktop (with G45) using xorg-server
184.108.40.2062, mesa 7.8.2 and xf86-video-intel 2.11.0/2.12.0 (with pageflipping
On another desktop having an ATI X300 card and using the open source radeon
driver, window previews are correctly shown.
I hope someone could look into this issue. I am of course available to perform
the tests you may require.
