Subtitle justification issue
I justify my subtitles to the left. When properly configuring this option under:
Preferences > Input / Codecs > Subtitle Codecs > Subtitle justification
to left, subtitles are positioned to the left, but the text is still justified in the center. This is most obvious when two or more subtitle lines are rendered on-screen.
I tested on Windows with both SRT and ASS format subtitle files paired with multiple video container formats (.mp4 and .mkv), and the result was the same.
I should note that this did work properly in 2.x versions of VLC, however in the latest 3.x version as well as today's 4.0 nightly I tested on, the problem persists.
