Parallels goes black and requires reset to get back to normal after a few minutes of inactivity

I have noticed recently that when using one of my programs (Altium Designer) if I am inactive for 5 minutes or so, parallels will exit coherence and just be a black screen and I can't do anything until I reset the virtual machine. While it is on the black screen, Parallels reports 100% cpu usage (red icon in the top right). I have no idea why this is happening, any ideas?

Thanks!

 

hi adinA, are you running altium on a M1 mac?
win10 for ARM + intel based Altium designer 21??
how is the performance? and how about the 3D views?

 

Yes, M1 MacBook Air.
I resolved my issue by upgrading parallels, and I am now on windows 11.
Before, and now, the performance has been just fine. Very smooth moving around schematics and layouts. 3D works perfectly as well.
