If you have performance issues with OpenGL/EGL/GLES read this

Hi everyone,

 

I was experience some strange things with two similar devices, the first I installed in february this year, mesa v.24.x and EGL 1.4 and it was working fine

The other one I installed this week and it turns out that it uses mesa v.25.x and EGL 1.5, although performance was great with most 3D apps (like glmark2) I had poor performance under sway/kitty or the retroarch menu for instance (something like 15 fps).

 

It took me a few days to find a solution so if you have similar issues please try installing mesa with the kisak repository as it fixed my problems

sudo add-apt-repository ppa:kisak/kisak-mesa -y
sudo apt update
sudo apt upgrade

the last command should upgrade mesa to a more recent version than what's in the ubuntu ppa.
