The subtitles on my TCL Roku TV sometimes blink in and out when a fast moving scene happens. This occurs in multiple streaming apps.
The subtitlrd will become hard to read, disappear for a few seconds and go out of sync. Since it's happening in several apps (Netflix Hulu, disney plus). I'm wondering if it's an issue with the TV itself?
These things are just special purpose computers, and just like their big brothers, sometimes operational problems cans be solved by a system restart.
From the Roku home screen use menu path Settings > System > System restart. (On a Roku TV the menu path is Settings > System > Power > System restart.)
