Monitor loses signal on fullscreen application, picom blackscreen

Hello there,

I'm struggling with an issue where my monitor loses signal when I put an application into fullscreen with i3 and ly.
This issue can be solved by starting picom, but that in turn gives me the same problem as described here
They might or might not be related, I'm not quite sure how to start my quest here. For some reason, X did not create a logfile, nothing at /var/log.

This is my picom config:

# Basic settings
backend = "glx";
vsync = true;
use-damage = true;

# Opacity settings
inactive-opacity = 1.0;
active-opacity = 1.0;
frame-opacity = 1.0;

# Shadow settings
shadow = false;

# Fading settings
fade = false;

# additional settings
glx-no-stencil = true;
glx-no-rebind-pixmap = true;
xrender-sync = true;
xrender-sync-fence = true;

# Logging
log-level = "warn";

This is what my picom spams out every milisecond or so when returning from suspend:

 gl_last_render_time ERROR ] GL error at line 1168: 1287

Found this issue describing the same problem.

To be sure that I didn't mess up my installation somehow, I just reinstalled arch and the same thing happened immediately. Seems to be a recent thing, can't remember when it started though.

I might be fine with a hook for restarting picom, but the fullscreen issue is a bummer.

Cheers:)
