Comment (by antoniou79):
I haven't had this issue on my devices or on the Android emulation.
I'll make a note to look again into the code for touch gestures and see if
cursor co-ordinates are not set/maintained properly.
A cursor "jumping" issue could occur for multi-touch gestures because the
co-ordinates of the first finger were kept -- this is a known issue that I
thought I fixed, but it can still occur in certain edge cases. Not
snapping to top left corner though.
Could it be that the issue is a side-effect from another third party app
on your phone or perhaps a touch screen (faulty) hardware issue?
Or a result from rogue dust/dirt on the screen?
There are options way to enable a visual indication of touch gestures in
the Android Developer settings (For my phone those are: Show taps (show
visual feedback for taps), Show Pointer location (show touch co-
ordinates)).

There are also apps on the Play Store that could possibly provide some
info on the issue -- if it's unrelated to ScummVM. Examples:
Touch Screen Test:

Touchscreen Calibration:

Could you test with the Developer option setting for visual feedback
and/or the Android apps to see if we can get a better idea of what is
happening?
