Bug summary
When opening thunderbird on a monitor with lower scaling in a wayland-session and moving it to a monitor with higher scaling-factor, it crashes with the following message in the journals:

- Set monitor 1 to scaling 100%
- Set monitor 2 to scaling 125% (or higher, if not available)
- Open Thunderbird on monitor 1 and move window to monitor 2.
This issue has been observed on three devices so far.
What happened
Thunderbird crashed, when moved to monitor 2, which has a higher scaling than monitor 1.

Thunderbird should not crash when moving from displays with different scaling.

The following line (about 3142) seems very suspicious to me:
