Describe the bug.

1. Have a multi-monitor setup with mixed scale factors. Eg. one monitor at 100% scaling, a second at 200%.
2. Open Tenacity and drag it around. On one monitor Tenacity will be the correct size, the other it will not be. It does not adjust the scale factor dynamically like GTK apps.

I have taken videos of what happens. Note the effect is exagerated here, since I usually have both monitors at 200% I had to create a weird setup and scale one to 100% to actually show the issue.

Expected behavior

Tenacity adjuts to the scale factor of each monitor akin to GTK. That is what the user expects, and that is what most apps should do.

OS

Fedora 34 Wayland

Additional context

It seems Tenacity arbitrarily picks one monitor's scale factor to match. The only app off the top of my head which behaves similarly is Steam.

This is likely an upstream wxWidgets bug.

Or is this a GTK issue? wxWidgets does not support GTK4; it is still on GTK3 and I doubt that will change for a long time. Do GTK3 applications usually adjust when switching to monitors with different scale factors?

GTK 3 also supports adjusting to monitors with different scale factors, I just tried it.
