I'm having tearing issues after shifting to Focal. At first I thought it was just on Firefox, but now it seems any full-screen video would tear up. I guess it has to do with the windows manager since compton has been removed from the list of WMs in MATE Tweak.
On Bionic I had tearing only in Firefox and that could be solved easily by just changing a config key.
Anyone else facing this problem? A solution would be much appreciated.
Okay I got a solution and it's working for my Intel graphics. I placed a config as in /etc/X11/xorg.conf.d/20-intel.conf with the following contents:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
EndSectionYeah, managed to find that nugget on a third-party website (not entirely related to Ubuntu) and the result was what you'd expect. It's a shame this config file isn't already in the base system as it's such a small change which does a lot to improve video quality.
This is a very old-time solution that I haven't had to use for some time. Didn't imagine that I have to revert back to it now; I don't understand why the "tearing free" isn't enabled by default.
