The two issues here (HEVC artifacts and Out of Memory crashing) are things we’ve previously reported to Hisense as platform issues, we’ve reached out again to see if there is an update to these problems.
It appears these are both direct play issues and disabling direct play (which will fall back to direct streaming or transcoding), in video settings of the Plex app should work around the issue for the time being; this isn’t a solution, but merely a work around.
If you can share the model numbers of the TVs you’re using that will help Hisense determine if it’s limited to specific models.
