The bug is that we have a FIFO underrun. FBC plays on > the safe side and disables itself in case we have a FIFO underrun. > > We should fix the FIFO underrun. I've seen FIFO underruns everywhere, > including in CI, so this is a known problem. The fact that the flickering stops after FBC has been disabled may implicate FBC. Do we have an option to force FBC to stay on despite underruns? That could help in figuring out whether FBC is just the victim or the purpetrator.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
