Comment (by Peter Bennett <pgbennett@…>):

 Fix is in the below referenced pull request

 These fixes optimize the softblend process in several ways.
 1. Prevent blending OSD into frames that will be skipped.
 2. Multi threading designed by LVR to speed the OSD blending.
 3. Eliminate merging of areas of the OSD that are either opaque or
 invisible. For invisible areas: skip, for opaque areas: overwrite, instead
 of existing code that calculates a merge every time.
 Performance with OSD is now almost perfect.
