About then, is when I'd see if the pattern 'changes' with the placement of Dock on the Screen.

As matter of curiosity, &/or minor test? [experimental] Check/change 'desktop image' too.


Because your Mac is new "M1 Silicon", the controls differ from Intel-based Macs; in an older

Intel-mac, you could try and see if SMC (system management controller) or NVRAM resets

would offer input; to see if any changes happen.


But with M1 Silicon, those won't do much of anything. What you can try with an M1 Mac

are some items suggested in following article; these pertain to M1 w/ macOS & its Recovery.


• Use macOS Recovery on a Mac with Apple Silicon - Apple Support

https://support.apple.com/guide/mac-help/macos-recovery-a-mac-apple-silicon-mchl82829c17/11.0/mac/11.0


One relatively simple item to try, can be to start in Safe mode. See M1 instructions here..


Start up your computer in safe mode

  1. Choose Apple menu > Shut Down.
  2. Press and hold the power button on your Mac until you see “Loading startup options.”
  3. Select a volume.
  4. Press and hold the Shift key, then click Continue in safe mode.
  5. The computer restarts automatically.


..these vary from those for Intel-mac. (there's actually 'two articles in one,' on this topic).

[the ''use macOS recovery ... with Apple Silicon'' article has M1-specific details]


Like other instructions (until fully new Silicon overtakes older ones) some show two

ways to do things; an example to bookmark: "How to use Safe mode on your Mac".

[Has 'both instructions' in one article. There are other ones like that, too.]


This is not a cure-all -- mostly it's a troubleshooting step -- to check/test the Mac.

While this is also an example of the different items can be run under M1 recovery.

As stated in previous reply; troubleshooting tip(s) that could help..


"..the (M1) controls differ from Intel-based Macs; in an older Intel-mac,

you could try and see if SMC (system management controller) &/or

NVRAM resets would offer input; to see if any changes happen."


For this matter, instead of details aimed toward resolving M1 Apple Silicon

this combined article blanket covers 2 or 3 troubleshooting chores in one.

[Plus mentioned instruction to perform Safe boot mode, in following too.]


• How to reset the Mac's NVRAM, PRAM, and SMC | MacWorld

https://www.macworld.com/article/224955/how-to-reset-a-macs-nvram-pram-and-smc.html


The Apple article about SMC reset(s) covers more details & other versions;

but not M1 Silicon. ~ Apple's Intel-Mac SMC reset approaches it differently.


Sometimes if asked politely, a few days may not make a huge difference

to an Apple genius or repair depot to Get hardware help to resolve issues.

With specific time frames; written guarantees, those limit flexibility in this.
