MacBook Pro A1989 display glitches randomly (vertical and horizontal lines, bottom half of screen goes black). It seems to happen when using too many resources, I believe. It's random and hard to recreate. Has anyone seen this? Does anyone have a fix?

We have-
1. Reset SMC.
2. Reset PRAM.
3. Installed latest updates (currently on Big Sur, issue also on High Sierra).
4. Turned off Color Filters. Turned on Color Filters.
5. Turned off True Tone. Turned on True Tone.
6. Turned off brightness auto adjust.

Thanks in advance.
