Hello,

I'm running Fedora 33 on a Dell Laptop and performed the steps in Quick Start to build and run in release mode. When I run, a window pops up and content is shown for a few seconds. Then the following stack dump appears and the window closes. Any ideas would be very much appreciated!

./mach build -d
./mach run -r -- https://github.com

I switched from X11 to Wayland in case that was the root cause.
It still crashes but get a different stack trace and no Window this time. See below:

This is not F33 specific but rather Servo.
I'm running F32 and I do see it in master (8c2ea9f).
It was not happening in 17a6c16.
Furthermore it only happens once you hover the mouse on the window. Smoke test runs fine.
