Recently upgraded my system only to have sway crash with an egl error, which was odd, given that I’m on an Intel GPU. At first it seemed to be a glvnd bug, as noted from the sway issue tracker, but it turned out to be a mesa bug. Can be worked around with WLR_RENDERER=pixman sway which uses software only rendering.

Another issue was having to handle the groups on the /dev/dri/renderD128 which needed sudo usermod -a -G vglusers $USER.
