--- Comment #4 from remirosent...@gmail.com --- I have found what's causing the issue for me. I apologise for not being able to explain this issue very well and for the narrow scope of the issue. I have a second IME installed (Google Japanese Input to be specific) which unsurprisingly interferes with input into Krita. As long as you don't switch between keyboard languages while Krita is open, the behaviour won't occur. If you still want to reproduce the issue then try downloading a Google Input tool then switch between inputs while Krita is open. In my case it seems using any Japanese input type except Direct Input causes all modifier keys (including shift, control and space) to no longer work even when switching back to the default keyboard. Sorry to have raised an issue like this but hopefully what I've found will be of help to someone. -- You are receiving this mail because: You are watching all bug changes.
