Hello there.
I have encountered this strange issue with the display . I am not sure what this is and I don’t know what to call it to find similar references.
It doesn’t happen with all applications and seems to happen at random with select applications.
Apparently this bug wasn’t captured on recording when I used screen recording or screenshot and the display was also glitch free while the recording software was active , so recording it by an external camera was my only option to show the issue.
Here’s the inxi output

I had kernel 5.4 installed and tried running it , but the issue persisted and became a bit worse on some applications while it improved on some other applications.
