Timeline not seekable on sections where a GL effect is applied to a clip.
- Add a video, cut it into pieces
- Apply any GL effect to a fragment. Square Effect and Squeeze Effect and the Twirl Effect and the Bulge Effect are effects causing problems.
- Try jumping into an area of the timeline where such an effect is applied. This results in the red marker jumping back either to last location or the beginning of the timeline.
It does not seem to matter if it's a H264 mp4 file or a VP9 webm file or other video file. Version tested is master from yesterday.
A video showing this probably is for now at https://yoona.everdot.org/linux/piviti/2019-05-12_18-23-44.webm (not a website, just some folder I have with random files that's is readable from the Internet's, not some permanent website. it'll probably be there for years anyway).
It isn't possible to play areas of the timeline where GL effects are applied either. Playback just stops when it gets there.
