Hi, somewhere during the Plasma 5.14 and/or KDE Frameworks 5.53 development
cycle, the openGL rendering backend for Plasma has become completely unusable
on both of my laptops with regular Intel graphics due to the extreme graphical
glitches. One runs Leap 15.0 with the latest Plasma and KDE Frameworks repos on
top, whereas the other runs straight Tumbleweed, and they both recently
starting having this issue, which is why I suspect something is wrong with
Plasma and not the Intel Xorg driver. I'm attaching hwinfo for the one running
Tumbleweed, but it's just a basic reliable Thinkpad T530 with Intel graphics.
I'm also attaching a video of the graphical glitches.
