Using a Strafe RGB MK.2 keyboard issues still exist with the latest release.
When you hit ESC it types 1 2 instead.
Zero macro's are configured and a completely fresh install performed (roaming profile cleaned out). Latest firmware on the keyboard as well.
This has occured for the last 2 releases.
I have now rolled back to 3.21.88 and have no more issues.
