I have added rotate=180 to the cmdline.txt and have one generic monitor attached (upside down mounted).
cmdline.txt: ... video=HDMI-A-1:1280x1024M@60,rotate=180
At the console and GUI the orientation is right.
In the console (e.g. gpm) the mouse follows the movement on the desk as expected.
However, when using an UI without X/Wayland the mouse is inverted (ie. all directions opposite to the expected movement) and is shown upside down.
This is an image with X and recent SDL testwm, but the same effect happens when running testwm from the console.

When using xrandr -o inverted within X and disable the rotate= from the cmdline.txt the mouse movement is as expected but I don't want to use X with the RetroPie setup as it might cause knock-on effects.
Has someone else encountered this by chance?
I am trying to find the root cause for this: Does the Rpi report wrong values or does SDL misinterpret the values?
