It seems that Firefox running under Debian Bookworm arm64 on Parallels has issues rendering certain web pages. In particular https://duckduckgo.com/?t=h_&q=foo&iaxm=maps is a reliable reproducer. Trying to open it freezes the Firefox UI, and the page is not rendered.
This happens only if drm hardware acceleration with virgl is enabled (the default):
Disabling virgl hardware acceleration (Hardware -> Graphics -> Advanced -> toggle Enable 3D acceleration), the page is rendered correctly and the UI does not freeze.
The bug seems to be specific to the way Parallels uses virgl, and not a general problem with virgl itself. Under UTM using qemu and Display Card virtio-gpu-gl-pci, which enables virgl, there are no issues.
A fix for running Bookworm under Parallels is to upgrade mesa and dependencies from bookworm-backports. See https://backports.debian.org/Instructions/.
