I've been using Edge Beta and Dev channel, and it has been awesome!
I have encountered some issues regarding opening PDF file and taking screenshots. Especially, I'm using multiple monitors and only one monitor - BenQ EW3270U, which I turned HDR10 on - is causing the problem. I'm also using Edge version 78.0.276.2 and Windows 10 v1903.
1. If I open PDF file on HDR10 monitor, the pdf file looks very dark. However, if I move the Edge window to other monitor, which does not support HDR10, or if I turn HDR10 off, the PDF file looks normal. It applies to all PDF file, not specific one.
2. If I take a screenshot while Edge window on the HDR10 monitor, the color on the captured image file changes very bright and it is hard to recognize the content. If I move the window to other monitor, or turn off HDR10, then also, it works fine.
I wonder this could be issue with HDR10? Thank you.
