Bug: Starting appimage creates visual artifacts on firefox appimage

[agreedSkiing]

What happened?

When using the firefox flatpak, haven't tried this with the native install, and then starting the archipelago appimage the borders suddenly appear on the firefox window.

After then closing all firefox instances and relaunching firefox a border has now been created around the firefox window

After closing the archipelago appimage the border persist in the second image. Firefox looks by default like below

Addition info

If I close the archipelago appimage when the first visual bug happens the window is returned to its original state.
