Wayland session freezes computer after login when "Zoom" accessibility function is enabled
Steps to reproduce:
- Enable "Zoom" functionality in "Universal access" menu in Settings.
- Reboot computer
- Login into Wayland GNOME Shell session
What happens: After the top panel and wallpaper (or sometimes even before wallpaper) is rendered the computer freezes:
- mouse cursor does not move
- I cannot switch to text terminal using CTRL+ALT+F3
- computer does not even respond to Num Lock key (the led stays always on)
- if I connect to the computer over SSH before logging in the remote terminal freezes too
If I press ALT+SysRq+S (Emergency Sync) the disk status led blinks. I can also see that the sync was completed in the system log. However there seems to be no other useful records in the log (see the attached journalctl.log; the SysRq keys were pressed after the freeze).
The freeze does not occur if I disable the "Zoom" functionality. It also does not happen if I start Xorg GNOME Shell session instead of Wayland session.
