Description

Version

v2.6.3

Platform

Windows 19

Steps to reproduce

I have 3 monitors, and 1 monitor will always have the software disabled for just that 1 screen. I have to disable/enable then it works again. I'm not sure how to reproduce, but it keeps happening. It might be a post lock screen issue? How would I try to narrow down how to reproduce? Is there error logs?
