Decided it was time to upgrade, and hoped that I could finally use hardware acceleration, which I had always been lacking.
I updated from Mint 18.1, to 18.3, to 19 with the 4.15.0-33-generic kernel.
I am now on lightdm, per the requirements for Mint 19.
After upgrade to v19, and 4.15.0-33-generic. I noticed an abysmal video judder on any framerate, even the native 60fps.
Media player of choice is Kodi - I had to compile it, as the apt version keeps throwing some kind of error about pcrecpp.
I compiled both Kodi 17.6 and 18 out of different prefixes.
- "Disable compositing for full-screen windows" is checked.
- All desktop effects that I could find in "Effects" are disabled.
- Wireless adapter is disabled.
- Tests were done with both VAAPI enabled and disabled -- seems worse with it disabled.
- Sync playback to display is on; Adjust refresh rate at start/stop.
- Kodi 17.6 - judders and stutters every 2-5 seconds. There seem to be an occasional skip backwards of a frame or two.
- Kodi 18 - stutters for 1 second every 5 seconds almost like clockwork. At every 5 second mark, there's the backwards frame skip which I would describe as judder, followed by what would seem as Kodi trying to compensate (stutter) for a second after.
Now on to the kernels where I tested this on...
I still have:
- Linux Mint 19 Cinnamon, with Linux 4.4.0-53-generic
- Linux Mint 19 Cinnamon, with Linux 4.10.10-041010-generic
- Linux Mint 19 Cinnamon, with Linux 4.13.0-39-generic
- Linux Mint 19 Cinnamon, with Linux 4.15.0-33-generic
Strangely enough, 4.10.10-041010-generic and 4.13.0-39-generic (which I didn't notice any problems with before) are now exhibiting stutter & judder on both Kodi 17.6 and Kodi 18 @ 23.976 and 60fps.
As a side note, maybe related, but x11vnc crashes on window resizing with 4.15.0-33-generic, whereas no crashing is present in the same manner on 4.4.0-53-generic.
Any suggestions to try to get the newest kernel stutter-free?
Current inxi -Fxz ... (if I need to boot up in 4.15.0-33-generic and report the same, let me know):
