Sudden and intermittent changes in external monitor colors

I am using a Macbook Pro M1 running Big Sur and two different external monitors (an ASUS VG289 at work and an Iiyama 22" at home) and I have the same issue on both: I have a rather close match on all my monitors (as much as these very different monitors allow), but suddenly the color changes, with more contrast and saturation and randomly reverts to how it was. This sometimes happens just by selecting a tool, or moving a layer. It becomes impossible to know which color is the right one. Additionally, the whole image flickers when drawing a selection.
This happens regardless of what Color calibration I use, or whether the image is in RGB or CMYK.

    First, try disabling GPU in the Preferences (Performance preferences). Any better?
    If not and this is happening in Photoshop, go to Preferences > Technology Previews... and check "Disable Native Canvas" - then restart Photoshop. Better?
    If not, recalibrate and build a new ICC display profile, the old one might be corrupted.
    If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.
    If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it. On the Mac, that's part of the OS update(s) so if this is the latest OS version, you may need to roll back a release.

    This doesn't appear to be a color management problem. I would look at reloading the OS first.  Then resetting Photoshops preferences on close. (In General pref's.) Then also look at the monitor connections.  All the common things to both displays.
