Illustration of the wrong (scaled down) app scale
Hello,
I have a laptop with an external screen.
The screen of the laptop has a resolution of 2560*1600 (150% scale) and an
external screen at 3440*1440 (100% scale).
When I open an some apps (with the lid of the laptop open or closed) and then I
close or open the lid, app resolution is wrong (either too big if I close the
lid or too small if I open it), resizing the window does nothing, if I
reopen/close the lid the resolution of the app is back to normal, if I
close/reopen the app the resolution is correct.
STEPS TO REPRODUCE
1. laptop with the lid open
2. Open an app
3. Close the lid of the laptop
OBSERVED RESULT
The resolution if scaled up too much
STEPS TO REPRODUCE
1. laptop with the lid closed
2. Open an app
3. Open the lid of the laptop
4. the app is now badly scaled
OBSERVED RESULT
The resolution of the app is too much scaled down
EXPECTED RESULT
Correct scaling of the content of the app
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 6.1.4
KDE Frameworks Version: 6.4.0
Qt Version: 6.7.2
Kernel Version: 6.10.3-arch1-2 (64-bit)

ADDITIONAL INFORMATION
The problem was also present in previous versions of kde.
It seem like the wrong screen scaling is picked.
I've noticed this bug with krita (5.2.3), discord and vscode.
If both screens have the same scaling the problem does not appear.
If I close and reopen the app without moving the lid, the app resolution is
correct.
