1816431 - Missing mouse cursor when sharing a screen on Wayland

Status: RESOLVED FIXED

(Core :: Widget: Gtk, defect)

Steps to reproduce:

Mouse cursor is missing when sharing a window or a screen under Wayland using PipeWire desktop capturer. This is because recent WebRTC no longer uses embedded mouse cursor and the information is sent separately as PipeWire stream metadata. For that reason a separate implementation of mouse cursor monitor was written, but it is not enabled in Firefox builds.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Attachment: Bug 1816431 - build MouseCursorMonitorPipeWire for wayland screen sharing

Mouse cursor is no longer embedded in PipeWire stream and is rather send
as a metadata. For that reason there is MouseCursorMonitorPipeWire which
is needed for mouse cursor to be properly updated and monitored.
