Description Piotr Budny 2019-10-12 18:59:32 UTC 
STEPS TO REPRODUCE
1. Vertically maximize window (e.g. middle mouse on arrow top right window controls) 
2. Resize window (e.g. with alt+right mouse button)
3. Try to move window (e.g. with title bar or alt+left mouse button)

OBSERVED RESULT
Window jumps down about half its size and then backs (on neon-testing).

On my local setup, window is getting maximized to full, looses window border (you can't grab to change size), it appears again after resizing window with alt+right mouse.

EXPECTED RESULT
No size change, no maximizing.

SOFTWARE/OS VERSIONS

Video describing bug

Bug is present in latest Kubuntu 19.10 with Kde Plasma 5.17.0 from backports.
The video shows that window 88x15. It gets maximized vertically (88x33), then resized grabbing top edge/border of the window to 88x8. The window now lacks of shadows around it.
Then, I'm dragging window (on titlebar) with mouse, the windows gets back to 88x15 (it shoudl be still 88x8), and gets back the shadows decorations.
