Weird scaling behaviour on some applications when dragged (Alacritty and foot)

[pamo22]

Describe the bug
When I set up two displays, one with a non-integer scaling factor, the application will for some reason scale itself a little bit (to match the scaling of the other window?). I've only seen this happen with foot and alacritty at this point.

To Reproduce
Connect two monitors to your computer
Set one monitor to a scale of 1.
Set the other to a scale of some non-integer value.
Spawn a foot or alacritty terminal.
Drag the created window.

Expected behavior
It shouldn't scale at all.

Are you saying this only happens with alacritty and foot from your testing? Or have you seen this behavior with others too?

[pamo22]

From very limited testing, yes. Only terminals seemed to be affected.

Also happens with Konsole. Does not happen with Kitty.

Edit: Also doesn't seem to affect WezTerm.

Probably related to #2331 (see especially the comments from me requesting improvements)

With #2331 wayfire now does the best it can to inform clients about what scale to use (fractional or not). If clients however change appearance when they change their scale, then this is a bug in the clients, not Wayfire. Closing
