#12532: Mouse Cursor Snaps to Top Left Corner on Android 8.1.0 Device

 I have a Contixo V8 Android tablet running Android 8.1.0. When I launch
 ScummVM, the application's mouse cursor repeatedly snaps back to the top
 left corner of the screen. This happens both in touchpad and direct touch
 mode. I verified the issue happens on the latest nightly build (I can't
 run the version command, but the in-app menu says "ScummVM
 2.3.0git16082-gd60abf0cc2 (May 10 2021 04:09:38)"). (The displayed version
 text has any descender segments of the font glyphs cut off; hopefully
 those "g"s are really "g"s.)

 The full experience looks something like this:
 - Launch the ScummVM app, arrive at main menu
 - Touch a location on the menu. Mouse cursor behaves appropriately as long
 as the touch continues
 - Lift finger from screen. Mouse cursor returns to top left corner of the
 screen

 I have also verified that this issue continues throughout the entire main
 menu (even while navigating through the settings dialog) and while in
 games as well.

 Curiously, the issue goes away temporarily whenever I open my notification
 bar by dragging down from the top of the screen. As long as the
 notification bar is visible, the mouse cursor will not snap to the top
 left. The moment the system hides the notification bar, though, the cursor
 returns to the top left if I am not in the middle of a touch action.

 I compared the behavior with a second Android device (Pixel 3 running
 Android 11) and the issue does not occur. It seems to be something strange
 with my Contixo tablet specifically.
