Rendering errors with libass, missing characters/shading ("Glyph bounding box too large") #53
Comments
Thanks a lot again. I hope we'll get back to this issue and decide what can be done about it. |
I’ve just tested the sample with FreeType git master (2c4832d3) on OS X (without any Infinality), and it still appears correctly. |
Thanks for the feedback. I'll update my comment. |
I found a video sample which causes a freeze in mpv and then a segfault, due seemingly to the same font-related subtitling issue: SAMPLE
Just thought I would post it before I forgot about it, and just in case it's of any use. |
Thank you very much. This is what we'll need for sure. If possible, please don't delete the sample so others willing to help can use it for tests. |

As stated on the BBS, if there's any additional information I've neglected to mention which would be useful, please just ask.
Update: I thought I would post my hardware and OS setup too, in case it might be relevant or useful:
