SUMMARY I just tried the newly-released 4.2.0 and discovered that I can no longer change the visibilty of layers, or lock/unlock them, etc. using my tablet pen. I'm an Intuos4 user. When touching the pen to the icons, they quickly blink off and then back on again. Holding the pen on the icons for several seconds does not have any different effect. The mouse works normally. STEPS TO REPRODUCE 1. Using an Intuos4 pen, tap the layer visibilty icon. OBSERVED RESULT Icon blinks off and then on again. Layer does not change visibility. EXPECTED RESULT Layer should change visibility and icon should reflect that. I've had to go back to 4.1.7 until this is fixed, as I'm constantly fiddling with layers, and it's too disruptive to switch back and forth between pen and mouse.
This bug still occurs in 4.2.1
Hi Autumn, I'm sorry, but I cannot reproduce the issue yet. Could you perhaps add the output of help->system information for bug reports to this report, and make a tablet log? See https://docs.krita.org/en/KritaFAQ.html#what-if-your-tablet-is-not-recognized-by-krita Do you have any special configuration set for your tablet?
I figured out what was happening. I start the Krita appimage from a script (so I can have a menu entry in my DE) and at one point in the past I had to export the environmental variable QT_XCB_NO_XI2_MOUSE=1 as part of that script in order to get Krita to work correctly. Commenting out that export solved the problem. I imagine it's related to your updated QT version.
So its not a bug in krita :D, good thing you found the solution. Marking as resolved
