Hi Andrew -
I’m not seeing those issues here…

You will see the problem when you turn on any Windows contrast theme. They are called aquatic, desert, dusk, and night sky. (I use aquatic contrast theme, very powerful laptop, new drivers, no third-party plugins.) Similar bug was reported here: https://mcneel.myjetbrains.com/youtrack/issue/RH-81648
Thanks.

thanks @Curtis Wensley, This is working well now in 8.8.24115.22001
You are running 8.7 and this appears to be fixed in 8.8.

These bugs are still present in Rhino 8.8.
