On Windows 10 whenever I click the "Start a call" button it causes the entire slack app to become extremely blurry. Other apps do this too sometimes. It has something to do with how they are being rendered, maybe related to high-dpi support or something. I've tried disabling the high-dpi support and enabling compatibility mode but it doesn't have any effect. Even after I close the "start a call" dialog the blurriness persists. It doesn't go back to normal until I restart Slack. Any ideas what is going on? I can't find any working fixes for this in Slack or any other apps where this also happens. An interesting thing I noticed was that in Unity (game dev IDE) when I set the render method to anything but DX9 it causes this same blurriness. Only DX9 makes it render sharp. DX10, DX11, etc all cause the blurriness. I just have a normal Windows 10 desktop, latest drivers & updates, GTX 1080 GPU.
