Not sure if this is the righ forum to report this kind of problems, but after this morning's `pacman -Syu`, I began to observe that Sway crashes each time DPMS is forced off, for example after `swaymsg "output * dpms off"`. Downgrading wlroots0.19 (0.19.1-2 => 0.19.0-5) and libdisplay-info (0.3.0-1 => 0.2.0-2) (and mpv) "fixes" the problem. Small excerpt from the system journal: wrz 24 10:07:01 ganges sway[1030]: sway: backend/drm/drm.c:1453: realloc_crtcs: Assertion `conn->crtc != NULL' failed. wrz 24 10:07:01 ganges systemd-coredump[1262]: Process 1030 (sway) of user 1000 terminated abnormally with signal 6/ABRT, proc> wrz 24 10:07:01 ganges systemd[1]: Created slice Slice /system/systemd-coredump. wrz 24 10:07:01 ganges systemd[1]: Started Process Core Dump (PID 1262/UID 0). wrz 24 10:07:01 ganges systemd-coredump[1263]: [🡕] Process 1030 (sway) of user 1000 dumped core.
