SUMMARY I really don't know why, but the very first Krita 6.0 prealpha carried a bizarre input bug which is still present in the current beta. Bug is as follows : for some unknown reason, the pen click input always repeats itself twice when you use the stylus. If for instance you want to hide a layer by clicking on the "eye" icon, it will flick, as if hiding, and showing itself again. On the menu bars, clicking on a button such as "File", "Edit", "View"... results in the drop down showing and disappearing quickly. Now this problem doesn't occur with mouse input. Stylus only, and is exclusive to krita 6.0 STEPS TO REPRODUCE 1. In an open document, create multiple visible layers 2. using a stylus, click on the "eye" icon to attempt to hide the layer 3. Try over and over OBSERVED RESULT The app never hides the layer because the input repeats itself twice. Click input seems to repeat itself twice using a stylus. And is thus compromised. EXPECTED RESULT The click input with the stylus should not repeat itself at all. SOFTWARE/OS VERSIONS Windows 10 Pro ADDITIONAL INFORMATION Tested on a Huion H1061P
Confirmed on Windows 10 with Krita 6.1 and Huion driver set to WinTab. No issue though with both set to Windows Ink.
