I will be back on friday. I just tried to bisect it, but it takes some time as the machine crashes on every restart of the X-Server... I will try to find the commit next saturday or sunday. The machine worked fine until i updated to factory from 11.0 final. So hopefully it is not much to bisect and every version compiles for me. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Previously, we were attempting to give both planes equal space in the FIFO to be fair. However, larger modes require more fifo space, so split it based on the relative HDisplay of the modes. This should resolve some fifo underrun issues with differently-sized displays, or single large ones. Bug #16169.
