Re: Screen tearing on TDE after open compositing

CPU:            AMD 8150 3.6GHz
GPU:            AMD HD5450 PowerColor
Motherboard: MSI 970A G43
HDD:            WD 1TB Blue
Monitor:        LG 1941

Even old motherboard happen as well. Screen tearing on XFCE
when open compositing window manager have been wideknown.
Users on XFCE DE solved this by install compton.
But I never thought this also happen on TDE as well.
Screen tearing will not happen only if I shut down. Which Q4OS usually turn it off by default.

I didn't report yet because it may be not Q4OS bugs but it might some reasons like this:
http://unix.stackexchange.com/questions … m-in-linux
Many ppl mention it had something to do with vsync.

Mate has had it fixed for quite awhile and XFCE also seems to be ok.

Yeah, I've heard some ppl solved by install kwin, compiz or compton.

Re: Screen tearing on TDE after open compositing

TDE uses own built-in compositor 'Compton-TDE', which is a fork of Compton, it works pretty well for most of hardware. Do not install other compositors, as it would conflict with. Your issue seems to be related to video driver or some driver config option.

Thank you for valuable information and proper warning I'll not mix it.

Anyway I've decided open ticket report bug already.
Also I've turned the compositor off to avoid screen tearing when viewing video.
