This seems to be a lot like the problems other people are having since upgrading Plasma to 5.21, but not exactly the same and different hardware.
My screen is flickering/vibrating all the time since reboot after updating today, which was the first one in a long time and also brought my Plasma 5.21, among other things.
I 'm guessing a fix will have to be specific to my hardware, so here are my specs:

Any suggestions?
It sounds like what I experienced last night after updating/rebooting. After I updated my system last night open windows, such as konsole, dolphin, firefox, etc., seemed to vibrate; moving up and down rapidly. A few weeks ago I was test driving EndeavourOS when they pushed out Plasma 5.21, and I remember reading about someone else having the same issue. So I found the thread, and found the person solved the issue. Here is the thread from over at the EndeavourOS forums: Since 5.21 there are glitches or something like that on my screen I tried the first option in the post marked as the solution (post #7 Solution ), rebooted, and it worked. The issue has something to do with onboard Intel graphics.
I saw that one before, but I wasn’t sure it applied to my hardware.
Tried both configs now, and the first one workde for me:
/etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
Option "DRI" "False"
EndSection
Kernel 5.10.19 has fixes for these graphics glitches. I made no other changes besides the newer kernel.
My system:
CPU: Intel i3-4150 (4) @ 3.500GHz (Haswell)
GPU: Intel 4th Generation Core Processor Family (HD graphics 4400)
Note: this is a Fedora 33 Workstation - I am assuming the fixes are independent of the OS.
I did a clean install and experienced flickering in SDDM and unresponsiveness in KDE, changing theme settings or adding a widget resulted in a crash of the plasma desktop. Plasma would crash on login, so deleting all config files was necessary to be able to get a working desktop again.
Adding these options to Xorg fixed it.
Here’s my hardware info:
