Same problem here, DVB-subtitle layer does not scale.

Sample file available here: https://www.dropbox.com/s/4voq6p56bv2l4to/sample.ts?dl=0
File is a clipped DVBLink recorded TVshow, a transponder file.

Console output:

BTW, that "too large" error and crash did not happen on a build I downloaded 3 days ago, it is not part of this reported problem so lets just ignore it for now.
