Description Martin Tlustos 2012-11-20 09:58:33 UTC 
When using slide transitions in my libreoffice presentation that have transparency included (like bleach, fade, etc.), it does not work - it hangs, flickers and then updates to the new slide without transisition.
opengl transitions seem to work.
Disabling hardware acceleration helps, but then other animations get slow, and the general quality goes down as well.

System: Dell Inspiron 1525 with intel 965gm, standard kubuntu 12.10 with desktop effects enabled (but disabling doesn't help either).

I thought the "hardware acceleration" option in libreoffice was a switch to use OpenGL and was known to be very buggy. Anyway can you please attach your Xorg.log?

xorg.log

So should I rather try and file a bug with libreoffice instead?

I don't see anything here to suggest a hardware issue (hang is such a pejorative word). The slow transition when not using "hardware acceleration" is entirely the fault of UXA, which is being replaced.

I would suggest first persuing the broken "hardware acceleration" transitions through libreoffice and then mesa/i965.
