Hello, I would like to ask your assistance in analysing my issue regarding on my issue that I was encountering when I try to play videos from Kodi that has subtitles where the display flickers every time the first appearance of subtitle. I tried to do it without subtitles and it worked perfectly fine.
I can play videos without any problem before the OS update of the TV, so I figured it might be due to the update. But I just want to try maybe somewhere in the settings of the TV that can be change or modify to avoid or fix this issue. I also tried multiple troubleshooting like changing some settings like true motion etc but did not work. Tried some also on kodi side like the subtitle settings and display settings but did not work also tried also the nightlies version of kodi but still did not work.
I will just try and maybe I just missed something or else I need to wait for the new update or use an external streaming device.
Below are the devices and apps that I use:
LG Smart TV 50 inches (4k)
Software Version: 33.22.56
Device Name: webOS TV UT8050PSB
webOS TV Version: webOS25 / 10.2.1-5205
Kodi Version Info (sideloaded using Web Developer Mode [using .ipk file])
Build: 21.0
Below are logs from Kodi also during the time where I play the video and enabling of subtitle:
