.ssa subtitles started to display incorrectly after upgrading to 3.0.19

[AndryS1]

Here's how subtitles was displayed on version 3.0.18.

But after updating to version 3.0.19 I got the following:

Log for this version: https://pastebin.com/VfbgNi5w

What I tried but didn't help: reset preferences, disable hw decoding, convert subtitle to codepage/utf-8 bom. Checked the nightly build dated October 21, same problem. I also checked the aspect ratio, it is set to "original". I have no idea what it could be.
The subtitles were originally in an mkv container, I extracted them with ffmpeg and the problem persisted.
I will continue to use VLC 3.0.18 until the problem is resolved. But I would like to upgrade to 3.0.19 if there is workaround for it. If any more information is needed I am ready to provide it as much as possible.

Subtitles to reproduce the problem can be found here: https://pastebin.com/up8SaLqF. Any 1080p video will do for testing.

Thank you for continuing to develop VLC

I can reproduce the issue while it's playing fine with other players.
You should create a new report ticket on the VLC issues tracker with your above report, the link to your sample file and the link to this thread:

If possible, because of this:

Thank you for your reply and for confirming the issue. I already tried to create a ticket, but got exactly the error you are talking about. Too bad you can't report a problem about logging in without logging in, ha-ha.
I will periodically check to see if the login problem is resolved and create a ticket. But if anyone here can do it for me, I'd be happy to.
Anyway looking forward to reporting the problem, thanks again for your replies.

Latest 3.0.20 have this problem too, in version 3.0.18 all are OK.

same problem here with .ass subtitles.

Rendering is correct here. Might be a windows only bug.

Did anyone tried to change video output ?

Bug is reopened, but can't reproduce

How does it behaves when you remove the

Same behaviour of stretched aspect ratio of subtitles with D3D11, D3D9 and OpenGL for Windows with VLC 3.0.20.
It's working fine with all other players I've tried.

I tried with my ass sub and without Original Script line it works... but it always worked even with that line (I think that's a default line for ass/ssa subtitles so it should work with it).

Exactly. It works with other players and it works with older versions of VLC so it's definitely a regression.

I see there are still no plan to fix this... why?
It is clearly a regression and it should be easy to fix...

3.0.21 or try nightlies

Can confirm, 3.0.20 nightly build (at least Dec 31) resolves the issue.
Thank you for your work and have a good New Year!
