I can see your point of view and I agree. I did update from 9.2.7 to the latest 19, hoping to fix it, but it didn’t work. I could have tried the nightly. However, I have been surprised by new bugs a few times now, resulting in a planned evening of watching a movie being canceled and me having to open up my case, flash eMMC, do config backups/restore, config file edits using SSH to make my remote work, etc. At this point I just want a stable Kodi player, nothing more, and 9.2.6 is that for me.
Now that it is outside of the case still, I could try the latest 9.2 nightly build. I will and let you know if it solves the issue.
I’m using CSL HDMI cables, which work fine for even my PS5, pushing 4K 60hz 4:4:4 over them.
