I still have the issue of the touchscreen being flipped on my Kobo Clara HD

I checked the update logs and it should be patched, but you may want to check that again. Many thanks!

I'm also facing this issue, there are no orientation options in app.

Ok, so I figured out how to fix. Edit the file in .adds/UltimateMangaReader/UltimateMangaReader.sh . On line 11 of that file, it should say:

export QT_QPA_PLATFORM=kobo:touchscreen_rotate=auto:touchscreen_invert_x=auto:touchscreen_invert    _y=auto:logicaldpitarget=108

Change that to:

export QT_QPA_PLATFORM=kobo:touchscreen_rotate=90:touchscreen_invert_x=auto:touchscreen_invert    _y=auto:logicaldpitarget=108

and it should work(at least it worked for me, so far). Essentially I am changing touchscreen_rotate to 90 in the startup file.
If it doesn't work or if have this issue on another device, you'd have to experiment with different rotate and invert values unfortunately. It took a bit of trial and error to find the right values.

I'm using a Kobo Libra 2. For me the issue is the screen being flipped also, I've tried replacing touchscreen_invert_xs value with 1 and touchscreen_invert_ys value with 0, though this may have caused the program to hang up

Okay, the line of code that worked for me is export QT_QPA_PLATFORM=kobo:touchscreen_rotate=90:touchscreen_invert_x=0:touchscreen_invert_y=1:logicaldpitarget=108

Kobo Forma, the touchscreen_rotate=90 worked.
