Thanks and you have nailed the bug for sure. Happy it worked for you. Mine is set at 200% (recommended) because of the resolution of my monitor - 4500 x 3000. Scaling it back to 100% on my system everything else is unworkable because it is too small. Everything is too small to read:
Desktop is unreadable
SketchUp menus and icons are unreadable is unreadable
Style Builder and Layout are unreadable
V-Ray is unreadable
Other design programs are unreadable (Photoshop, InDesign…)
I can get 2021 to work on my computer recommended 200% scaling but V-Ray is buggy with it. Support is more or less indifferent to my problem.
Thanks again
