Title:
Mir shows an old frame on client startup (for Mesa GL clients)
Status in Mir:
Fix Released
Status in “mesa” package in Ubuntu:
Triaged
Bug description:
Mir shows an old frame on client startup.
Test case (1):
1. Start and stop one client at a time:
bin/mir_demo_client_egltriangle -s 500x500
bin/mir_demo_client_eglflash -s 500x500
...
Expected: Each client only shows its own frames
Observed: The first frame of each client seems to be the last frame of the
_previous_ client.
Test case(2) - more definitive but requires hacking:
1. Insert a long sleep in your client code just before eglSwapBuffers
Expected: The Mir server never shows the client till after the sleep has
finished.
Observed: The Mir server composites the client immediately on startup, with
old/invalid pixel data. It only gets replaced with a valid frame after the
sleep finishes.
