Hi milkywaif,

> Right now I can't replicate this issue any more. It seems to be disappeared in Nov-19 beta.

Hmmm, this may just be a chance thing or maybe due to some other factor. Did you possibly update your video driver recently or switch off transparency for the Windows desktop theme or anything like that? Because as far as I know I haven't done anything in particular to solve this myself...

I've heard of this problem before from just a couple of people but I don't understand what would cause it, possibly some kind of video driver bug. I've never seen it myself.
