Well I can reproduce. Something or other to do with relative mode being enabled, this doesn't happen if relative mode is off.

Also doesn't happen if you do a very "strict drag" as in, mouse down, start moving mouse, stop moving mouse, mouse up. This starts to happen if you wanna do an "inertia" scroll by releasing mouse during the drag and then moving it elsewhere.

Was this so bad before?

@bdach What is related mode in this context? An android system setting?

[bdach]

It's literally the framework "relative mouse mode" believe it or not. Why it affects input in this way I do not know and did not want to find out hence why I left this issue be.

To me, it looks like clicking/moving the mouse is generating keyboard arrow key events.

The runtime log from OP shows: "Unknown SDL key: SDL_SCANCODE_SELECT, SDLK_SELECT". Which is AKEYCODE_DPAD_CENTER in Android: https://github.com/libsdl-org/SDL/blob/main/src/video/android/SDL_androidkeyboard.c#L97.

Nearby scancodes to that include the AKEYCODE_DPAD_{UP,DOWN,LEFT,RIGHT}, reported to us as keyboard arrow keys.

I'm unable to reproduce as my phone OS is bugged and doesn't properly support relative mode.

I am currently unable to reproduce this using the method described in the OP.
If you are saying this is a cross key input, is #31441 relevant?
