Whenever I attempt to undo or redo, about 1 in 5 times the attempt does not go through, whether it be via tablet buttons, keyboard shortcut, using the buttons on-screen, or even manually clicking through them in the undo history docker. I would attach a video but I’m a new user so I cannot, I hope this is an apt enough description. I can confirm that the tablet and keyboard do function with other programs, so I’m 99% sure this is a software issue. I am on Windows, Krita version 5.3.2.1
Hello @Mak_Rat and welcome to the forum 
You can post a link to a file download service to make a video file available.
Well do I feel goofy for not having considered that, thank you haha
