This problem has been plaguing me.
Around March of last year it was fixed. Then sometime around October the video
tearing started occurring again after an Nvidia driver update. I don’t have
driver version numbers, sorry.
I definitely believe it is an Nvidia driver issue. There is no screen tearing
on my late 2012 Dell XPS 13 Intel hardware with the same software setup and
open source Intel drivers.
Test video: http://www.youtube.com/watch?v=ceX18O9pvLs
Chromium bug report: http://code.google.com/p/chromium/issues/detail?id=160454
My current setup:
distro: Arch linux 64bit
nvidia 580 GTX: 310.19
Dual ASUS 24" monitors: Ancor Communications Inc. VS248
Things I have tried:
I have attempted to enable hardware acceleration in /etc/adobe/mms.cfg, but it
seems to do nothing.
cat /etc/adobe/mms.cfg # OverrideGPUValidation=1 EnableLinuxHWVideoDecode=1
Right clicking the test video linked above and selecting “Show video info”
shows “software video rendering, software video decoding”
Right clicking the video and choosing “Settings” and checking “Enable hardware
acceleration” has no effect.
“Sync to VBlank” is enabled in nivdia-settings, no effect.
