That sounds like a driver issue. You might want to look through the cvs history for suspicious changes. This one looks suspicious: http://cvsweb.xfree86.org/cvsweb/xc/programs/Xserver/hw/xfree86/drivers/mga/mga_video.c.diff?r1=1.35&r2=1.36&sortby=date The description says: 85. Fix for Xv resolution loss problem with Matrox cards (Michael Lampe). but, if I recall correctly, some of the resolution loss issues with Matrox cards were because the video scaler didn't have enough bandwidth to display the full resolution. Reclaiming the resolution in bandwidth challenging situations probably results in fifo underflows which, at least on the NVIDIA cards that I'm familiar with, would produce results like you are describing.
