On both Arch and Manjaro with Nvidia 380 or 390 series drivers snaps using hardware acceleration are crashing:
Spotify somewhat works but it takes long time to load and hardware acceleration is disabled.
Ohmygiraffe doesn’t work at all.
snap run --gdb doesn’t find stacktrace and
coredumpctl doesn’t show anything really useful.
Note: Solus with the same driver versions works fine.
