whole canvas view port slightly blinking to red

Hello :)
On an M1 macbook  with Sonoma 14.5 _
The whole canvas viewport (decoration included) blinks to a more red color after the computer sleeps.
- I don't remember observing it after a simple application switch so I think it's related to computer sleep.
- It always blinks to a reddish hue.
- I think it happens randomly like 10% of the time ? It's really a rough estimate I'm pulling off my head...
I have attached a mini video showing the blink.
Switching tabs doesn't stop it. I need to stop krita, which is very bothersome as I usually have multiple open tabs with selections in them to quickly pick palettes from older paintings (and guarantee color unity in my webtoon).

This seems like a graphics acceleration issue. Could you share your system info with us?
