video of normal vs incorrect behavior
SUMMARY
When using certain programs such as Kate or Konsole, and the global scale is
set to 175% or 200%, the mouse will grab the window instead of the scrollbar
when the mouse position is at the very right edge of the screen and the
application is maximized.
STEPS TO REPRODUCE
1. Display Configuration -> set Global scale to 175% or 200%
2. Log out and in again to apply the scaling.
3. Open Konsole
4. Type a commmand to produce a large list of files such as `find`
5. Maximize the Konsole window.
6. If you have multiple monitors, make sure Konsole is on the right most
monitor.
7. Move your mouse to the right edge of the screen, hold left click, then move
the mouse up or down.
OBSERVED RESULT
The window is grabbed and starts moving around as if you grabbed the title bar
to move the window.
EXPECTED RESULT
The scrollbar is grabbed and you can scroll the window, like you can when the
scaling is normal.

ADDITIONAL INFORMATION
It used to work correctly about a year ago. I'm not sure exactly when or what
component version broke it.
Attached is a video of the bug. At first it shows how it should work. The 2nd
clip shows the incorrect window grabbing behavior.
