Hi, after updating to the latest wacom driver (cintiq was acting strange a bit) Krita stopped responding to any drawing input, displaying the change only after minimizing and re-maximizing the window. Thus, I updated Krita as well in the hope of fixing the lag (now 3.1.2, previously 2.8.something i think), but the bug persisted. Win10 64x, Wacom Cintiq 27QHD, mail me if further information is required. Something seems to be incompatible there. Also, Krita seems to be missing a "check for updates" in the menu. Thank you very much, Sue
