Need to push X twice to swap between foreground / background color
I have a new issue recently that I would like to resolve.
I do a considerable amount of masking. Pushing X to switch between foreground and background black and white. I need to push it twice.
I find now very often that when I push X it does not immediately switch. I'm still painting with the same colour. I push X and the foreground has not switched. I need to push it again X. Then it switches.
I keep testing my keyboard and it's not the key. But when I'm working the foreground doesn't change when I push X the first time.
The first time I push X the foreground does not switch. I push t twice and it switches.
It's driving me slowly crazy(!)... Is this a thing?
