Bug Central (Apple doesn't care)

[-BigMac-]

Hi guys.

My iMac 2020 27" is slowly becoming unusable.

I have frequent software bugs, graphical glitches, and app crashes. This seems to be getting worse with every subsequent software update.
Every time I attempt to screenshot a software bug, opening the screenshot app resets it and appears normal.

So today, I decided to take a photo of the screen with my iPhone instead.

Behold, Apples newest and greatest Mac software version, on the beautiful 5k display:

Glitched out the dock, menu bar, half of safari, half app view... triggered by Cmd+Tab.

So.. I reported these bugs 4 months ago to Apple. 3 different reports. None have even been read

It might be a GPU problem.

Good suggestion actually.

Okay, just ran it, got ADP000 - No issues found.

Is there another way to test the GPU?

This looks like hardware issue. I’d take it to authorized repair center and have them diagnose the issue.

You could monitor the temperature with an app like Stats https://github.com/exelban/stats to see if it's overheating, while using a benchmark
