Comment (by joshas):

 There are more mouse cursor related issues in GOB engine games, probably
 very closely related to the one reported here. Many games have feature
 where mouse cursor is automatically "teleported" over first option of
 dialog, when it opens, e.g. the "Quit" dialog. Clicking "Quit" in game
 menu opens "Confirm/Cancel" dialog, and mouse is placed over "Confirm". In
 original game, or when it is running in DOSBox moving mouse cursor works
 as expected: it moves from current position, where it is at. But in
 ScummVM, including the latest 2026.2.0 version, mouse cursor is
 "teleported" to new location, but after moving mouse, it promptly returns
 to previous location, where it was before the dialog opened. It is even
 more annoying when using item menu: mouse moves over first item in
 inventory, but any movement brings it back to old location, making
 selecting items quickly a bit complicated, especially when inventory opens
 quite afar from initial mouse location.

 And in original bug report, mouse cursor is supposed to stop at purple
 dialog box. In DOSBox mouse cursor even hides behind dialog box, but never
 moves further down.

 I suppose this might be related either to Wayland issues, or because there
 is no "mouse capture" mode in ScummVM. While #9827 was closed as
 "wontfix", maybe this time we could try to come up with some better
 solution? Gameplay really suffers when mouse cursor works so erratically.
 I think scrolling is impacted by this issue too, as scrolling left in
 Goblins 3 is very hard to achieve when playing in window.

 Tested using Goblins Quest 3 (Interactive Demo 3 (v0.02)/DOS/English)

 GOG version of the game exhibits same bugs, but as executable was not
 provided, I could not test it in DOSBox.
