Fractal closes itself regularly
Several times per day, Fractal just closes itself without any warning. When I reopen Fractal, it works perfectly fine. I haven't reported it earlier simply because I'm very confused: it doesn't appear to be a crash, like I would expect. In particular, Fractal leaves no core dump in coredumpctl, so there's no way I can provide any further diagnostics. It's as if it's quitting itself intentionally.
I'm using the latest stable release, 4.0.0. I believe this bug is a "new" regression in 4.0.0, i.e. 3.30 was unaffected.
