Sorry for the long delay in responding - had to wait for some other things to finish so I could switch from Xorg to Wayland. The same types of pauses/lags/freezes happen to me under Wayland using mpv as were happening under Xorg. They may be slightly less frequent (subjective judgment, no actual

Sergei, "performance" is a general category of problems that includes dropped frames. For example, in gnome-shell I have separated those issues: https://trello.com/c/Q6JYXPPs from the ones that incur measurably high hardware usage: https://trello.com/c/pe5mRmx7 A low frame rate is still a

I've checked iowait using iotop during lags and revealed no spikes or something like that. So it's not a performance problem at all. I believe gstreamer is just dropping frames due to some bugs. I had 17.10 installed and had no issue that time. -- You received this bug notification because

One more thing: Wayland sessions might perform better, so please try mpv in a Wayland session. Unfortunately Totem probably won't work there (bug 1770725). -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu.

The pauses are very brief using mpv - using totem I still get pauses in excess of 5 seconds at random points during playback. However I am willing to accept that this would constitute a duplicate of 1698270, and will wait for any updates there. -- You received this bug notification because you

Thanks. If the pauses are now very brief with your BIOS in "fixed" mode, and if mpv is performing slightly better than totem, then I suggest this is now a duplicate of bug 1698270. Bug 1698270 is not fully resolved and requires more investigation. -- You received this bug notification because

Totem and gnome-shell both are running between 10% and 30% each (they bounce back and forth during playback). The next highest usage (according to top) is 8% and under. Is there a way to capture CPU usage during playback that will be representative of actual usage? My video resolution is 1920 x

Thanks, but there's no need to benchmark the CPU itself. We already know the CPU model. What does concern me about CPU usage is whether gnome- shell or some other process is using considerable CPU during playback. Do you find that? Also, please run 'xrandr' and send us the output. Gnome Shell is

Thanks. What you are experiencing is worse than I have ever seen. We do have a catch-all bug 1698270 to cover similar issues, but I am not aware of it ever being as bad as you describe. Maybe this problem is specific to the VAAPI decoding that is common to both totem and mpv... Does the problem
