Multitouch Malfunction Under Waydroid

[xiaozhuo256]

Environment:
Occurs when using Waydroid on Hyprland.
Hardware: Wacom touchscreen device

Observed Behavior:
Multitouch functions normally in native applications (tested with MS Edge) outside Waydroid. However, within Waydroid sessions, a specific multitouch failure occurs:

When holding one finger stationary on the touch surface and tapping with another finger, the initial touch point is lost.

Simultaneous multi-finger input works as expected.

Validation:

Verified this behavior does not occur on Sway using identical Waydroid setup.

Attached evidence：
Same problem from reddit
touch in hyprland
touch in waydroid(HYPRLAND)
waydroid(SWAY) tested by myself
waydroid (HYPRLAND) tested by myself

Conclusion:
This appears to be a Hyprland-specific regression in Waydroid touch event handling.
