Long videos occasionally visually stutter

[ObsidianPyro]

I've been using asbplayer to watch anime with subtitles for a while, and recently started doing it from media with the raws. I only just now have the issue when trying to watch a movie (82min) rather than a normal episode(24min). Occasionally the video stutters, clipping down a bit, and immediately jumping back up.

What I've tested:

• Just watching the video in VLC, the stuttering doesn't happen
• Watching it in asbplayer without subtitles attached, it doesn't happen
• Watching it asbplayer with subtitles attached but not in fullscreen it doesn't happen.

A video will be attached, although it's recorded from my phone. For some reason when recording with Windows 11's snipping tool I couldn't recreate it. The browser I'm using is Brave, and is up to date, with hardware acceleration on.

Just wanted to ad that I've had the same problem for a while. Seems to only happen in fullscreen. What i've noticed is that it happens everytime a new line loads. Hope this might help finding out what the problem is.

Thanks for reporting this issue. I'm tempted to say that this is a problem with Chrome's fullscreen rendering performance but it's hard to say for sure. Some things that you could try out are disabling any 'fancy' subtitle styles such as transparent background and text shadows.

So I have been researching a bit on my own, as this honestly is a very annoying issue. What I've found out is that it seems to be an issue when playing a video with a different aspect ratio from the screen. This is probably why [ObsidianPyro] only notices it with a movie, which seems to be in cinemascope 2.35:1. As for me, my laptop is 3:2, and the content is widescreen 16:9.
Connecting through HDMI to a screen with a 16:9 aspeect ratio, and watching on that instead, solves the issue, though playing a video in fx 4:3 makes the issue return.
Don't know what can be done about it, just thought i'd contribute with what I'd found.

Thanks for the info. If that's the case then one workaround I could suggest in case you haven't tried it already: Turning on theater mode (top right button that looks like a rectangle) and then fullscreening the browser itself (on windows F11).
