Continuing the discussion from Transparent mouse pointer help:
I had a problem yesterday which led me refresh my laptop running Roon (as a controller), please see link to previous post.
I have found out where the issue occurs. I use an HDR monitor linked to a Surface Book 2 running Windows 10. After I refreshed my laptop yesterday I found my issue resolved (the mouse pointer was no longer turning transparent). However today I turned on HDR in the Windows 10 display settings and the problem came back. I turned off HDR and the mouse pointer returned to normal again.
TLDR: When HDR is enabled in Windows 10 display settings it makes the mouse pointer turn transparent within Roon making it hard to see.
Not sure if this is a Windows 10 issue or if it can be fixed on the Roon end. Just thought I point it out, just in case it can be fixed (because I much prefer running with HDR enabled) or if it just helps someone else out having the same issue.
