Too many subtitles causes video to lag

[KojoZero 0]

When playing a video on my iPhone with lots of and/or heavily stylized subtitles, the video + subtitles would lag for a while (but audio still plays). This occurs even when I download the episode. The video runs perfectly fine through VLC (via UPnP) or when I disable the subtitles in Emby. Is there any way to fix this? I've attached an example video + server logs (no ffmpeg)

Extra Info:
IPhone SE 2nd Gen
iOS 14.6
Emby App 2.0.8
Emby Server 4.6.4.0

I've gotta say, the new design looks super slick! However, the problem still persists
