Enable xrender-sync-fence #2

Closed RafalSkolasinski closed 3 years ago

RafalSkolasinski commented 3 years ago

I was struggling with some very weird refresh problems with NVidia proprietary drivers: terminal (both tilix and alacritty) was failing to render proper output e.g. during cycling through history of commands and moving cursor left and right.

It seems that setting 

xrender-sync-fence = true

in picom config file fixed the issue.

This patch https://github.com/regolith-linux/regolith-compositor-compton-glx/commit/d9a4da6f84955ea2cc38354e964d9fd08fa92047#diff-2245023265ae4cf87d02c8b6ba991139R45 applies same option to compton config (that was my inspiration to try it).

Hi @RafalSkolasinski are you opening this issue to simply help others that may have the issue or are you suggesting adding this flag as default for all users?

RafalSkolasinski commented 3 years ago

Hey @kgilmer. I think it would make sense to put it as default. If you don't think it's good idea then for sure make a note on compositor's page in docs.

This was a significant blocker for me to get Regolith works on all of my machines: having a wrong information at random displayed in terminal was just a no-go. I think only on 3rd approach I managed when I found this option.

Ok I'll review the picom source regarding xrender-sync-fence and do some local testing.
