Infinite loop when opening app switcher with `enable-animations=false`
software versions: phosh 0.20.0 (built from source), phoc 0.21.0 (from Manjaro repos), libhandy 1.6.3 (from Manjaro repos)
As soon as I slide the app switcher open, I see sustained 100% CPU usage from phosh and the app switcher (e.g. window previews) and launcher no longer respond to touch events. I can slide the app switcher back closed, but then cannot open it subsequently. The top bar continues to respond normally through this whole process.
This also happens with libhandy 1.79.0 built from source.
Attaching with gdb at this point, I get various backtraces, all involving hdy_carousel_scroll_to_full:
