I think after the last updates from october I have a problem when playing any kind of videos.
It does not matter whether I play videos via addon, PVR or just a file. After about 3-4 seconds the refresh rate is switched. I set refresh rate switch in player settings to start/stop and delay after change in system to 0.5 seconds.
One vero4k+ is working with 1920x1080p@60Hz, the other with 3840x2160@60Hz.
Both switch after 3-4 seconds.
To get a better understanding of the problem you are experiencing we need more information from you. The best way to get this information is for you to upload logs that demonstrate your problem. You can learn more about how to submit a useful support request here.
Depending on the used skin you have to set the settings-level to standard or higher, in summary:
enable debug logging at settings->system->logging
reboot the OSMC device twice(!)
reproduce the issue
upload the log set (all configs and logs!) either using the Log Uploader method within the My OSMC menu in the GUI or the ssh method invoking command grab-logs -A
publish the provided URL from the log set upload, here
Thanks for your understanding. We hope that we can help you get up and running again shortly.
