(Tried to google and to nugde the iRC community to no avail.)
Impress 6.4.0.2, Debian sid x64, nvidia latest closed diver, dual monitor.
None of the “3D” transitions work at all, black flickering (on VCL:gtk3, nothing on gtk2 or x11) screen only. Preview won’t do anything either, only waiting, then nothing. Non-3D transitions work.
No matter what’s “hardware acceleration” or “anti-aliasing” setting I pick. (Also worth mentioning that OpenGL - The Document Foundation Wiki is outdated and the sttings mentioned does not seem to exist anymore). This possibly has been going on for long time now, but now I would like to use it.
