It is impossible for me to see actions on the canvas, not even the cursor follows my movements and when I draw something the brushstrokes only becomes visible when I click at something at the menu.
Outside of the canvas I dont have that problem. I already tried to reinstall it 2 times and I deleted the kritarc folder but it still wont work.
Haven't got that problem with other software.
I excuse for unclear language, english is not my first language.
Please, please -- please do check the faq and existing bugs. We know! Microsoft has recently brought out an update that breaks Krita in opengl mode on systems with an intel gpu:
Disable opengl for now, please.
My own systems aren't affected (yet) so I haven't been able to look into whether a workaround is possible at all, or whether we should just disable opengl on any Intel/Windows system.
It is either this... Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB4013429) or this: Update for Windows 10 Version 1607 for x64-based Systems (KB4013418)
Please tell us exactly which brand and model of system you have, and which version of display chip and display driver you have. For the driver version, press the Windows key, then type "Device Manager", open the Device manager application and check the Display Adapter dialog.
