X11 scaling in KDE is causing a display issue.
I have recently tried to use the KDE scaling with X11. After setting it to 150%, and restarting the computer, Kdenlive now scales down the displayed footage inside the display area.
Screenshot to save me the 1000 woords:
Arch has just been updated, and it looks like the way the screen sizes are being reported after a scaling has been altered from what I experienced before.
