Created attachment 17372 [details] xorg.conf Setup - I have notebook LCD panel (primary monitor, 1440x1050) and external LCD monitor with panel 1600x1200 connected via DVI to dock-station. "shakes" - like some reset occurs in hardware There was no such glitch when second head was VGA monitor with lesser resolution (probably bug is related to bug #16513). Sometimes effect is lesser, sometimes harder. Sometimes just scrolling window entirely on primary head leads to such effect xrandr --off and then configure again for second head helps a bit. $ xrandr Screen 0: minimum 320 x 200, current 3000 x 1200, maximum 3040 x 1200 PANEL connected 1400x1050+0+0 305mm x 228mm 1400x1050 60.0*+ 74.8 60.0 1920x1200Scaled 60.4 1920x1080Scaled 60.5 1600x1200 85.0 75.0 70.0 65.0 60.0 1600x1200Scaled 60.4 1680x1050Scaled 60.3 1600x1024 60.0 1400x1050Scaled 60.3 1440x960Scaled 60.4 1280x1024 85.0 75.0 60.0 1280x1024Scaled 60.5 1280x960 85.0 60.0 1280x960Scaled 60.4 1280x854Scaled 60.4 1152x864 75.0 1280x720Scaled 60.4 1152x768 54.8 1152x768Scaled 60.3 1024x768 85.0 75.0 70.1 60.0 43.5 1024x768Scaled 60.4 832x624 74.6 800x600 85.1 72.2 75.0 60.3 56.2 800x600Scaled 60.3 768x576Scaled 60.4 854x480Scaled 59.8 720x480Scaled 59.8 640x480 85.0 72.8 75.0 59.9 640x480Scaled 60.1 720x400 85.0 640x400 85.1 640x350 85.1 320x240Scaled 57.6 320x200Scaled 55.7 VGA_1 disconnected DVI-D_1 connected 1600x1200+1400+0 408mm x 306mm 1600x1200 60.0*+ 59.9 1280x1024 75.0 59.9 1280x960 59.9 1152x864 75.0 74.9 1024x768 75.1 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 75.0 72.8 66.7 60.0 720x400 70.1

Could you please retest with the latest git version where these debug lines are gone?
