Electron Version

What operating system are you using?

Other Linux

Operating System Version

Arch Linux Plasma 6 Wayland

What arch are you using?

x64

Last Known Working Electron version

22.3.27

Expected Behavior

For the window to not resize when focus is changed and to fill screen properly when maximized.

Actual Behavior

I have a 2 screen setup where the secondary screen to 90% to better align with the size of the primary screen(125%). On the 90% screen when Electron is on it will not properly scale to fill the screen and when I click on another window the electron window shrinks. Alternating between the 2 windows will continue to resize it smaller and smaller. The window also does not maximized properly. This behavior does not occur when fractional scaling to at 100% or 125%.

Experiencing same issue with the BitWarden desktop client with wayland scaling <100%.

GUI elements are also not scaling properly--they scale visually, but positioning and mouse events seem to be based on unscaled sizes. It is unclear whether that is a bitwarden or electron issue.
