is a know problem of bad segment package pts / selection, mainly for HLS because pts that come from segment packages are differents form the manifest pts of subtitles

this bug influence also this value https://github.com/xbmc/inputstream.adaptive/blob/22e17ca10674f7a7fd4b05eb4c13bb327b7905c1/src/main.h#L67-L69 used to seek subtitle stream when re-enabled then when you turn off/on subtitle happens bad behaviours with segments

a good solution require not easy changes on more components from my part atm i have no time thing to do in a future or by someonelse

PS. attach hundred of files in a Issue thread is nonsense, compress all them in a single file
