Subtitles make the video jitter

It has happened a few times on different videos: whenever there are added subtitles like srt, whenever the subtitle line/dialogue changes, the video lags for a split second. This happens on every new line/dialogue.

The video runs fine without subtitles.

What is your device model and Android version?
Could you please share some logs? Reproduce the issue and then go to: Settings > Advanced > Debug logs. Then share the logs with the sharing service you prefer (Google Drive, Dropbox, pastebin...).

Please follow the my guide to export the logs. Yours are not useful unfortunately.

Reproduce the issue and then go to: Settings > Advanced > Debug logs. Then share the logs with the sharing service you prefer (Google Drive, Dropbox, pastebin...).

Sorry for the late answer. You don't seem to have reproduced the issue before generating the logs. Please do.

Also, does it happen if you remove the "Video match frame rate" setting?

"Match display frame rate" option is off, still the problem is same.

The problem has not been resolved for me in version 3.5.3. Still get choppy video every time new subtitles pop up on the screen. (Android TV 11)

Hi VLC Team
Same problem here.
VLC v.3.5.3 on Xiaomi Mi TV p1 (android 10)
I’ve tried some different options but the problem persists.
Thanks for your support!

PS: found a topic when some others talk about it:

I talked with @unidan and it seems that subtitles performances will be improved in VLC 4 only. Sorry for the inconvenience, but you will have to wait for this future major version.
