Electron Version

31.0.1

What operating system are you using?

Ubuntu

Operating System Version

Ubuntu 22.04

What arch are you using?

x64

Last Known Working Electron version

28.3.3

Expected Behavior

screen.getCursorScreenPoint() should return the correct position of the mouse even when the mouse cursor is out of the main window or the mouse event is pass-through.

mainWindow.setIgnoreMouseEvents(true, { forward: true });

Actual Behavior

screen.getCursorScreenPoint() doesn't return the correct position when the mouse is out of the main window.

I can see that this method is working on MacOS (with v31.0.1)

Additional Information

I think this is the same issue with #41496.

This was working until the last version of v28, which is v28.3.3. However, since the first version of v29 (29.0.0), it hasn't behaved the same as v28.x.x.

v28.3.3

v31.x.x+

If I set pass-through with setIgnoreMouseEvents, mouse position capturing doesn't work regardless of transparent window or not.
v31.x.x+ (with setIgnoreMouseEvents)

mainWindow.setIgnoreMouseEvents(true, { forward: true });

Note that I am using X11 window system on Ubuntu 22.04.

That behavior change prevents from using the workaround method for 'Support click-through of transparency #1335' (#1335)
