This topic was already discussed in few topics on this forum, like here: https://forum.videolan.org/viewtopic.php?f=14&t=117007
But a solution like "switch subs off, then take snapshot and enable subtitles again" is just a workaround.
I need to take around 20-100 frames from 24-minute videos every day, that's why I really need a hotkey for that. There is one in MPC-HC and mpv, for example.
It becomes especially irritating when I find many topics like "snapshots are now being taken without subtitles" with answers like "oh, that's a bug, we'll fix it right away". Hey, thats's exactly what I wanted!
