Hmm happens in 2 completely different OSs that are definitely using completely different driver builds and code to interact with the card. Clocks are not the issue.
I call out the issue is actually with the monitor especially if it’s a green screen. If possible try a different monitor. or a different refresh. Most of the issues people are seeing like this or issues with power draw on idle, flickering refresh, etc. are due to monitor manufactures fudging the specs and actually running the monitor outside of VESA standards.
The other thing to check to see if your monitor has a firmware or driver/profile update.
Heck it can even be a subpar hdmi/Displayport cable.
