Troubleshooting • KDE Plasma not filling entire screen on a 4K Monitor

I just set up Raspberry Pi OS in a Pi 5 and installed KDE Plasma that comes with the operating system. When I boot the SDDM, the display fills the entire screen. When I login and Plasma loads, there is a huge black bar on the right side of the screen. The black bar shrinks the higher I crank up the scaling, and is completely gone when I set it to 200%. But I want to run it at 150% or 125%.

My Google skills are failing me, so I am posting here hoping someone else has gone through this.

Also, is there any way to run KDE 6 on Raspberry Pi OS?
