Same issue with 2 x GTX 1080. Problem gone after disabling "hardware accelerated gpu".

This is similar to #78377 and #78584 (both deal with multi-GPU and with that Windows option set).

Considering the issue has been reported multiple times now, I think 1) Users experiencing problems should report the problem to Microsoft using their Feedback app since it's influenced by this setting and 2) Investigated here just in case blender's calling pattern is problematic somehow.
