Created attachment 110131 [details] bug log with debugview which presents [BLOCKED] whenever I tried drawing I have a Lenovo Yogabook, which features an integrated drawing pad or tablet. The program never recognized pressure sensitivity, but I could draw normally. However, when I tried to draw today I found out that drawing with the pen is impossible. The pen works fine to select brushes and enter menus, but it doesn't work in the canvas.
Please update to 3.3.3
Similar problem here: I have a Acer Chromebook Spin 11 (that has Wacom pen) that supports Linux apps with the latest Chrome OS 69. I installed Krita and it works with an external USB Wacom tablet as expected (but no pressure senistivity support). But when I use the Pen that comes with the Chromebook, I can only use the pen to control Krita (Menüs, Function selection, etc. but it doesn't draw anything on the paper/canvas. So that's strange: the pen of the externel USB Wacom tablet can draw (on its tablet), but the pen from the Chromebook drawing on the screen can not draw. But the Chromebooks screen pen can do anything else in Krita. (By the way: the graphics programm "Gimp" on the same Chromebook does not have this problem, i.e. both the USB Tablet pen and the Chromebook's screen pen can draw in Gimp on the paper/canvas.)
