[Wayland] Delayed event.is_released() outside of game window

[Damglador]

Tested versions

• Reproducable on Godot v4.4.1.stable.arch_linux

System information

Godot v4.4.1.stable unknown - Arch Linux (KDE Plasma Wayland as DE) #1 SMP PREEMPT_DYNAMIC Fri, 09 May 2025 17:20:29 +0000 on Wayland - Wayland display driver, Single-window, 1 monitor - Vulkan (Mobile) - integrated AMD Radeon Graphics (RADV RENOIR) - AMD Ryzen 5 5600H with Radeon Graphics (12 threads)

Issue description

I have Emulate Touch From Mouse turned on and use the following function to get start and end point of a drag:

var startpos = null
var endpos = null
func _input(event: InputEvent) -> void:
	if event is InputEventScreenTouch:
		if event.is_pressed():
			startpos = event.get_position()
		if event.is_released():
			endpos = event.get_position()
			_launch(startpos, endpos)

When end of drag is inside the game window, it passes it to _launch in no time, but when it's outside of the window - it takes a second or so. This issue is not present on X11 or Windows builds of the game run under Wine in Wayland native mode

Steps to reproduce

• Enable Wayland in project settings
• Enable Emulate Touch From Mouse
• Use the code below in a node of a scene
• Click and hold LMB in the game window, move it out of the window and release it

func _input(event: InputEvent) -> void:
	if event is InputEventScreenTouch:
		if event.is_released():
			print("End of drag")

Hi, thank you for your report! From a quick look I have a feeling that this issue might be deeper, as in, that this might boil down to how we handle pointer input in the first place.

I just did a quick test and it indeed looks like we are not sending button release events while leaving the window, so you might as well even got a bit lucky getting a release in the first place :O

I think this might be totally related to #105908.

I'll take a look shortly!

I made a PR which tracks button releases properly when the pointer goes outside the main window: #106414. Please tell me if this fixes your issue :D

Yup. After some tweaking with the AUR package was able to compile the patch, it fixes the issue. Thanks!
