Description J Jones 2018-02-18 00:24:25 UTC 
I would like to use this program, but for some reason when it starts up it rotates my entire desktop upside down!

I am using a Wacom Cintiq and I rotate the desktop so the controls are on the right.  There is no need for this program to take over the whole computer and rotate it without asking first.  

Thank you

Please provide the output from Help->Show system information for bug reports.
Comment 2 Alvin Wong 2018-02-18 05:53:02 UTC 
For the record, it is very likely due to this Qt bug report: https://bugreports.qt.io/browse/QTBUG-49541
Certain drivers may crash if the screen rotates when OpenGL is in use, therefore Qt would disable screen rotation on those drivers.

If you go to "Configure Krita"->Display and change the Renderer to ANGLE, it should allow screen rotation normally.

Windows: Reset screen rotation after probing QPA OpenGL

If the Windows QPA OpenGL blacklist has disabled rotation for the
device, it does not reset the screen rotation preference and as a
result the screen orientation will remain locked in landscape even if
ANGLE is enabled or the QPainter canvas is used.

This change works around it by resetting the screen rotation after
the QPA OpenGL probing. The display might still be forced into landscape
for a split second during startup, but it is better than being locked
entirely.
