Alacritty works as root, not user

Hi,

I've been using Alacritty for a while as a regular user but it stopped working a little while ago. Still fine if I run it as root though if I run X, start an xterm, 'sudo bash', and then run alacritty.

The output from glxinfo | grep -i opengl :

I also tried removing the Alacritty config; that didn't make any difference to the results.

Re: Alacritty works as root, not user

Not sure how this relates to success with root but have you looked at https://github.com/alacritty/alacritty/issues/4491?

Re: Alacritty works as root, not user

Oooh, that's a weird issue, but yes, creating a ~/.drirc with the vblank_mode set to 1 has resolved it. Thanks!

Re: Alacritty works as root, not user

Same story here, Alacritty suddenly stopped working. I'm glad I've found a solution after approx. 2 months of figuring out what is wrong. Thanks
