I’m using several addons to download subtitles, they were working fine when using LE (kodi 17.6).
With CE 8.99.2 (SD card, Minix U9H), I noticed a lot of below warnings:

WARNING: CRenderManager::WaitForBuffer - timeout waiting for buffer

and the subtitles script simply cannot fetch URL anymore (not sure if linked to CE and Kodi 18 though)

But I found this fix for LE.
Can I try it on my build ? I’m not sure which file should I modify to test it.

Thank you
