Hey there!
If I were taking a bet on this, based on everything you said, I’d bet that you are experiencing a bug with an old build of Razer Synapse/Chroma. Razer has since fixed it but you probably still have the old data on your Win10 build.
If that doesn’t work, my next best guess would be out of date drivers or windows. Double check those for me?
If you’re still having trouble after this troubleshooting, please generate a text copy of your DxDiag using these instructions. Once you have that made, open the file. Copy the code below, then copy/paste everything from that DXDiag file between the rows of tilde (~) marks where it says “DXDiag goes here.”
