On my Android phone, zooming in and out of the QR code area of the attached PDF file makes yesterday's Firefox Nightly 126 and today's 127 unresponsive. I can also reproduce the issue in Firefox Release 124 for Android. I cannot reproduce the issue on Windows. I managed to capture some performance profiles but cannot do that very reliably since the issue can make the profiler unable to complete. The profiles are sometimes missing screenshot information, or information for some processes.
Profiles when zooming on the QR code area:
https://share.firefox.dev/4cVSEr3 (Nightly 126)
https://share.firefox.dev/4cZBoRz (Nightly 126, no screenshots / missing GPU?)
https://share.firefox.dev/4aWx0Bi (Nightly 127, no screenshots / missing GPU?)
https://share.firefox.dev/3UjK7XK (Nightly 127, + many threads + IPC)
Profile when zooming on another text area of the same document, which still produces unresponsiveness but seems more easily recoverable maybe:

This may have the same root cause as bug 1890537, the PDF file linked there also makes Firefox unresponsive for me when zooming in/out.
