UI hang, 100% CPU usage #12
Description
Hi,
This is on version v0.3.1, running on NixOS - I'm aware you've got a newer version, but I don't have a chance to try this out right now and thought you may be interested in the report anyway. Please feel free to close this issue for any reason.
I've used btdu a fair amount without problems. Today I tried applying it to new disk, larger than I normally use it on, which is NVMe. I observe a hang (instantly) after ~1000 samples (not repeatable exactly), where the UI subsequently doesn't update nor respond to input.
CPU usage remains at 100% though. I captured the following report of what btdu is doing using sudo perf record --all-user --call-graph dwarf,65528 -F 100 btdu and perf report.
