[Android] Video stutters when subtitles enabled

Description

I have an Android TV v10. When I play a video file (e.g. a regular 1080p h264 in an MKV container) through VLC app without subtitles enabled then it plays butter smooth. Once I enable subtitles (contained in the same MKV container, not from an external subtitle file), then the video starts stuttering. In particular, it seems to drop frames whenever a new subtitle paragraph is rendered.

After googling, this issue seems to have been around for years. This issue does not affect VLC for iOS or macOS (I tried both). This issue also does not seem to affect other video players on Android. Can someone please fix this? VLC is awesome. Thank you!

Expected behavior

When subtitles are enabled, then video should not stutter.

Actual behavior

When subtitles are enabled, then video stutters.

Steps to reproduce

Open any mkv video file with included subtitles
Start video playback without subtitles -> video plays perfectly fine
Enable subtitles -> video starts stuttering
