picom infinite loop on GL error after wake from suspend

[kociap]

When waking the computer from suspend (systemctl suspend), picom fails to display any graphics due to an error.

gl_last_render_time ERROR ] GL error at line 1168: 1287

1287 corresponds to 0x507 which is GL_CONTEXT_LOST. This causes picom to enter an infinite loop occupying 100% of a single thread. The log picom.txt

I've managed to make picom recover from the error (patch reinit.txt). The recovery takes only a few ms, yet any graphics show up a few seconds after the cursor first appears. Until then the screen remains black.
