Thanks for your reports! It’s definitely odd for this to happen for this many folks here and with the greyscale/desaturated icons. It sounds a bit like drivers may be the culprit since only happening in Heroes.
Please try a clean uninstall of the current video drivers using the DDU tool, here’s a guide. If you’re using an AMD card, could you try rolling back the drivers to 19.12.1 here? We’ve seen some issues with AMD drivers recently where it causes freezing, beeping, and crashing issues due to Radeon Chill or the 19.12.2 drivers.
I would like to compare graphics, BIOS, hardware, and windows version for a bit more information. Would each of you be able to provide gather a DxDiag file? Copy and paste the text file created and paste it between two ~~~ like so:
