I see 18.9.1 suggests the issue is fixed. NOT! But it is a bit better.
If you drag your mouse across a couple screens a few times it will pause every time.
It's not like it used to be but still annoying even on start menu.
FWIW I installed over the top of 18.3.4
I used device manager to rollback and things are back to normal. Of course now I have to uninstall and reinstall the older version because radeon settings doesn't match. :/
Please try for yourself and post your results.
