Pointer coordinates and orientation wrong for absolute/indirect pointer devices #619

Open Saviq opened 5 years ago

Steps:

run ubuntu-core-vm
install mir-kiosk
edit /var/snap/mir-kiosk/current/mir-kiosk.display to rotate the display
snap set mir-kiosk cursor=software

Notice that the cursor plane is rotated along with the screen rotation instead of being counter-rotated to remain absolute.

The current behaviour is correct for a normal mouse. I'm not clear what's being seen with tablet input..

Ok. This is a slightly obscure problem: It's that input coordinates are incorrect for absolute, indirect input devices (such as graphics tablets), not for direct absolute input (such as a touchscreen).
