not sure though if it segfaults on suspend or on wake up. could be the same issue as the #902.

i'm on arch linux, running xfce 4.18, gtx 1650 w/ nvidia-dkms 525.85.05-1. hmu if you need any additional information, i'll respond asap.

looks like it happens only with egl backend:

$ ~/Documents/picom/build/src/picom --config=/dev/null --backend=egl
[ 01/24/2023 18:54:57.880 get_cfg WARN ] The egl backend is still experimental, use with care.

doesn't seem to happen with the nouveau driver. nvidia :angry::angry::angry:

GLX error at line 479: GL_OUT_OF_MEMORY

Seems like an issue with EGL

[absolutelynothelix]

decided to try the new open-source nvidia driver called nvidia-open. after suspending it crashed and hung the entire system so i had to force reboot my pc.

[yshui]

maybe a driver problem then? :thinking:

[absolutelynothelix]

@yshui, since the segfault happens somewhere in the nvidia's driver libraries, i believe so.
