I have two screens, one's scale factor is 200%, the other's is 100%. Not sure if it's related.

Comment 2 Nate Graham 2023-09-07 16:54:27 UTC

Hmm, cannot reproduce with one screen at 200%, or two screens with one at 200% and one at 100%. Wayland P6 of course.

outputconfigurationstore: add new config system

Instead of an external service (like KScreen) storing and restoring output configurations,
with this commit KWin takes over that responsibility. This allows it to, among other things,
generate appropriate configs for new sets of outputs immediately, and take KWin-internal information
about outputs into account when generating them.
