System Info and Version

git @ 1423707

Description

If more than one layer surface with keyboard interactivity exists (screenshot tools across multiple monitors, keyboard interactivity to kick focus out of games that lock the mouse), clicks will often be released immediately for seemingly no reason.

How to reproduce

1. Have at least two monitors or run a nested session with two. The bug does not trigger with only one.
2. run the below quickshell tester. (quickshell commit 67783ec24c61030abff8ba5008a5bbd2822c6eca guaranteed to work)

quickshell tester

import QtQuick
import QtQuick.Layouts
import QtQuick.Controls
import Quickshell
import Quickshell.Wayland

ShellRoot {
	Variants {
		model: Quickshell.screens

		WlrLayershell {
			id: layer
			required property ShellScreen modelData;
			screen: modelData;

			anchors {
				top: true
				bottom: true
				left: true
				right: true
			}

			color: ma.pressed ? "#20005050" : "#20202020"
			layer: WlrLayer.Overlay
			keyboardFocus: WlrKeyboardFocus.Exclusive
			onKeyboardFocusChanged: console.log(`kbf: ${keyboardFocus}`)

			MouseArea {
				id: ma
				anchors.fill: parent
				onPressed: console.log("pressed")
				onReleased: console.log("released")
				ColumnLayout {
					anchors.centerIn: parent

					Button {
						text: "close"
						onClicked: Qt.quit()
					}

					CheckBox {
						text: "Keyboard Focus"
						checkState: layer.keyboardFocus == WlrKeyboardFocus.None ? Qt.Unchecked : Qt.Checked
						onClicked: layer.keyboardFocus = layer.keyboardFocus == WlrKeyboardFocus.None ? WlrKeyboardFocus.Exclusive : WlrKeyboardFocus.None
					}

					TextField {}
				}
			}
		}
	}
}

Crash reports, logs, images, videos

All clicks in the video below are drags, however hyprland causes it to be released early most of the time.
