I use a logitech g203, but im not using the logitech software
Hmm. I don’t currently have access to a Logitech g203, but I’ve tested with a variety of other models of Logitech mouse, and was still not able to reproduce this issue. It’s possible that this issue is specific to that specific model, but I’ll need to test it to be sure.
However, given that the issue doesn’t affect other models of Logitech mouse, it seems more likely that it has some other cause.
