SUMMARY Returned to my project to see all my subtitles failing to render. STEPS TO REPRODUCE* 1. Update system files (restart) 2. Create new subtitles (or load old ones) OBSERVED RESULT Subtitles failing to render, "[filter avfilter.subtitles ] Unexpected return format" error detailed in Effect/Composition Stack EXPECTED RESULT Subtitles rendering, no error. SOFTWARE/OS VERSIONS Latest EndeavourOS Arch build, latest KDE Plasma version as the desktop environment. ADDITIONAL INFORMATION This error does not occur in the appimage version, which is what I use now. (Ty KDE Matrix chatroom) * I do not know the exact steps to reproduce this, and I don't have the knowledge to figure it out without spending hours figuratively breaking a brick wall. All I know is it happened after running a system update and restarting.
