Delete branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
(This is probably not very actionable, but seemed worth recording somewhere.)
On the first run of the boids example, I saw it working for ~20s and then it crashed with this error message. I haven't been able to reproduce it since.
This is on nixos 22.05 with the shell.nix from https://github.com/hexops/mach/issues/192#issuecomment-1083516343.
Again:
Seems very non-deterministic, but happens much more often with the gkurve example.
Notes:
So seems likely to be an issue with mesa drivers rather than with mach.
