XInput2 causes erratic mouse behavior with two XScreens
scfarley opened this issue · 3 comments
Following commit 91edd21, the in-game mouse behavior became erratic where the mouse would
attempt to control the move the view within the game on one screen but keep the cursor on a different screen. However, this only happens on :0.0.
My system has two XScreens (:0.0 and :0.1). At any menu inside Minetest, there is no issue. If I run the game on :0.1, there is also no issue. The mouse stays with the game on the same screen and all is good.
If it is played on :0.0, then it is erratic. The mouse is mostly seen on :0.1. While dragging the mouse, the game flickers (painfully) a lot as it spins the view looking straight up. It is as if something is confused about where the mouse should be in relation to the game window. Could it be only considering the display and ignoring the screen (:<display>[.screen]) in making a decision about the mouse cursor?
I have tested Minetest 5.6.0 with IrrlichtMt 1.9.0mt7 with and without this commit so can confirm the issue is related to XInput2.

Be sure to denote 2 XScreens rather than 2 screens because this stuff gets confusing/misleading faster when you consider you can have more than one screen (monitor) on one XScreen ;)
