Caption editing leads to huge lag
I don't think this issue is exclusive to the Beta - but when editing captions on the timeline, there is huge lag
The lag disappears if the caption track is hidden...but that makes editing almost impossible
Other solutions (clearing cache, zooming into timeline) don't have a significant effect
CUDA or software doesn't have a significant effect
Further weirdness - the lag is only there on ~2/3 of operations. Sometimes it's fine, but then out of nowhere a simple text selection will take 10 seconds
Happens on sequences of all sizes (eg current sequence is ~220 captions)
All media / prj files are on local high speed SSD media
