Do you have blur enabled? If so, try to reduce the blur strength. For me, it seems that some sort of clipping occurs if the setting is too high so that all blurred parts become distorted. Well... in my upgrade from linux 2.6.34 to 2.6.35, the problem has changed... Now the transparency looks OK but when the fade is enabled, and a menu appears it start transparent, goes to half opaque, then blocks for about 1 second and finishes opaque. I don't know if it is related to my original bug report... Disabling blur did not solve the problem. I do not use KDE, so it is not clear to me what is wrong on the screenshot. Please also attach the screenshot how it should look like, so that we can compare.
Here's some advice on how to bisect efficiently.
Your driver is usually located in something like: /usr/lib/dri/r300_dri.so
Delete that file and make a new symlink r300_dri.so in place of the original file and point it to .../mesa/lib/gallium/radeong_dri.so, where mesa is your git-cloned mesa repository.
Here I have:
$ ls -l /usr/lib/dri/r300_dri.so
lrwxrwxrwx 1 root root 47 2010-05-23 21:22 /usr/lib/dri/r300_dri.so -> /home/eosie/dev/mesa/lib/gallium/radeong_dri.so
Now when you just compile the driver ("make"), it will be automatically used by all applications you run, and those running ones should be just restarted. Concerning KDE, you probably want to restart kdm after typing "make" in the mesa directory. It's really that simple. Now there is nothing stopping you from bisecting. ;)
Hi, Thanks for your advices on bisecting, I did not even think of symlinking >.> Anyways, it looks like there is some kind of bug, sometimes KDE says it can enable effects and after when reverting to a working dri driver it never wants to enable it again... I'll have to sort this out... Anyways, the transparency problem is solved (on a kernel update ?) And the other issue I reported, (the lag in the fade effect) also seems to be gone... I don't understand how... I' attach a screenshot of how it is now (partially fixed ? transparency is OK but why don't I have the thumbnail of my window ?) Created attachment 37591 [details]
transparency ok
thumbnail at the center is missing, I don't know why. I'll have to find out if it's related to KDE or r300g
OK I confirm the thumbnail bug is not in kde but in r300g I'll post a screenshot with swrast_dri.so. Created attachment 37598 [details]
with swrast thumbnail OK
