Description Viorel-Cătălin Răpițeanu 2019-01-29 23:48:30 UTC

SUMMARY
Draging a maximized window when a 1.5 scale is applied will result in it moving it's origin point (instead of restoring it to an unmaximized state).

STEPS TO REPRODUCE
1. Add 'BorderlessMaximizedWindows=true' to your kwinrc
2. Add a 1.5 scale for your output
3. Open an application that supports dragging from within itself (like KDevelop)
4. Maximize it. (the border should be hidden now)
5. Click inside your application and drag and drop it else where.

OBSERVED RESULT
The application remains in a maximized state (with it's border hidden) while it's changing it's origin point.

EXPECTED RESULT
The application should return to a window mode (unmaximized), before changing it's origin point.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 5.14.90
KDE Plasma Version: 5.14.90
KDE Frameworks Version: 5.54.0
Qt Version: 5.12.0-3

ADDITIONAL INFORMATION
This was tested using kwin for X11.

Hmmm, can't reproduce. Could you please post your kwinrc and breezerc?

> 2. Add a 1.5 scale for your output
So... This happens only with 1.5 scaling factor, right?

This reproduce on 2 different computers with 1.5 scale. This doesn't happen when there isn't any scaling (scale 1).

Created attachment 117744 [details]
kwinrc file

I don't have any breezerc file.

Comment 5 Vlad Zahorodnii 2019-02-07 00:56:57 UTC

Hmm, I still can't reproduce it. Also, I'm wondering how scaling could affect net move resize.

Can you please create new user with default settings from Plasma 5.23 and only make the configuration changes you describe below and let us know if the issue is still present. We need to be able to reliably reproduce the issue to have a shot at fixing it.
