Roku update 12.5 broke the Plex app

Here is a detailed response from Plex employee "ljunkie" today:

------

sorry, everyone, for the delayed response! We have been investigating the issue and have isolated this to some changes in the Roku 12.5 OS update, specifically memory issues with MPEG2 streams in an HLS container. Roku enforces apps to use up to ~300MB of memory. Once an app goes over the threshold, Roku will terminate the app, which is what we are running into while direct streaming MPEG2 with a resolution of 1080. Lower resolutions are not immediately affected. However, those streams use much more memory in this scenario than they should. We are looking to see if we can do anything to limit the memory usage, but this may be something that needs an OS update/fix from Roku. The playback stack and memory management are part of Roku’s OS, which developers cannot tune or modify.

In the meantime, to work around the issue, we will turn off direct streaming of MPEG2 if the resolution is over 720p. While the “Allow MPEG2” setting is not technically supported, you can still benefit by enabling it for resolutions lower than 1080p. If the Live TV channel is 1080p, the setting is ignored and will require a transcode to convert from MPEG to H264 (essentially, what happens with the setting disabled). We will be publishing a preview update shortly and plan to include this change in the next official release.

I have the same exact problem!  Please fix!

When only playing back 1080i content saved from the HD homerun, or when streaming live TV that's 1080i from the HD homerun, after a few minutes, the Plex app just crashes, and goes to the Roku homescreen. 

This happens only with my 5 Roku streaming stick+'s.  I've purchased these in 2020, 2021, and 2022.  They are not the same batch.  

This happens with any of the settings changed in the Plex settings section.  I meticulously changed each one at a time trying to figure out what the cause is. 

This DOES NOT happen with an old Roku 3 I purchased in 2016.  It's running the same Plex software version as the above.  I've tried both WiFi and network.  This one doesn't have the problem.  

All of my other streaming apps on the Roku work perfectly, even at 4K (on WiFi).  e.g. Netflix, Hulu, Amazon prime, Disney+, Discovery+, Pluto.  It's only the Plex app that gives me the issue.  

I've used theses streaming sticks for 3 years, or so, and never had a problem with Plex. It started in October.  I think there was an update.  This royally messed up my Plex's ability to let me watch my live OTA content!

I even tried a different way to make my Plex server.  Instead of my Synology, I used an up-to-date Ubuntu desktop on the LAN.  I then used a Windows 11 machine.  The only thing that I have in common is the Plex app.  

I've tried different TVs, different HDMI ports, different USB power adapters for the Roku.  Nothing is the culprit.  Just the app. 

I can watch my content on my desktop computers without an issue.  

Please fix ASAP!
