-Subject: [PATCH] vnc: Drop frames if client is gone
-
-Frames from PipeWire are posted asynchronously from a I/O thread to the
-main thread where they are turned into VNC frame updates and cursor
-movements. On the other hand, sessions are closed asynchronously when
-the VNC client disappears. If a frame ended up on the main thread after
-a client disappeared but before the session and stream was closed, we'd
-try to turn the new frames into VNC updates without a client being
-available, causing use after free.
-
-Fix this by dropping frames that happens during this time frame.
