Full screen 1440p video stutter

Post by Adamsk1 » 2019-12-21, 12:50

I recently upgraded my monitor from a 1080p to a 1440p.
Any website that I play a video in full screen, (no matter what resolution, 480p, 720p, 1080p, 1440p) stutters a lot and resembles a very low frame rate.
Being out of full screen the video plays fine.
The monitor runs at 155hz and other browsers do not have this issue.
I have Radeon RX Vega.

Is this a limitation of the browser? Or can I change some setting to help this?

Thanks.

Re: Full screen 1440p video stutter

Post by Goldengsp » 2020-01-15, 22:48

I have this same issue of full screen videos stuttering though with some screen tearing in Palemoon on my 1440p monitor but not my 720p monitor. My setup consists of a newly built AMD based computer, Ryzen 2600x CPU, and Radeon rx590 graphics card, hooked up to one 1440 monitor and one 720p monitor. Stuttering is present on the 1440p monitor when full screen, but if i slide Palemoon to the 720p monitor and full screen the video there is no stuttering. Notably the full screen stuttering issue isn't present at all on my old Nvidia and Intel based computer. Both computers have windows 10 installed and are updated to the newest version of Palemoon. I have tried other browsers where the stuttering is not present.

Pale Moon is not a dedicated media player. It is a web browser. Its media capabilities are aimed at playing in-page videos of limited resolution and adaptive bitrates, not HQ home cinema playback.
If you expect buttery-smooth 1440p or 4k video playback, you'd better pack a hell of a lot of power per core and have the video delivered in a codec that can leverage hardware decoding.

stuttering occurs on my 1440p monitor while the video is playing at any resolution including 144p,240p.360p.and 480p while the video is in full screen. I'm not exactly trying to stream 4k if my internet could even allow it. Like OP it only occurs in full screen, while out of full screen the video plays fine.

If you have a multi-monitor setup then be aware that this can influence how hardware acceleration works (or doesn't work). That, however, is not something at the browser level as it would affect all applications, and needs to be solved at the driver level.

As for the OP's question: your troubleshooting information looks fine; you have full hardware acceleration and hardware x264 decoding going on so there isn't anything else to do on the browser side there either. Have you tested this with the new monitor in other browsers?

In the process of trying to troubleshoot this I have dropped multi monitor, soloed with two other monitors, and messed around with radeon settings. The stuttering only occurs when any video at any resolution is full screened within palemoon on the 1440p monitor with the AMD computer. it doesn't happen with my old Nvidia/Intel computer or an old Intel laptop I tried. I guess palemoon just doesn't like this monitor/computer combo.

Try Safe Mode. You have a dodgy extensions list (Adamsk1). Adblock Latitude together with uBO? The abandoned Complete YouTube Saver? Flash and Video Download? All of that can definitively interfere with playback. I would try a clean profile as well.

if you have the resources to, you might try a different GPU (video card) as your CPU generally has little to do with the video and seeing as you had no problems when using an Nvidia gpu based device.

In my case a least safe mode doesn't change a thing and this install is only a few days old with the stuttering in full screen happening from day 1. As for switching out gpus that's pretty much impossible for me.

If the problem is caused by extensions, it won't matter whether you installed them 3 years or 3 minutes ago. Try with a clean profile and also check your installed/enabled plugins (not extensions). Disable them and restart if you have any.

I haven't installed any extensions yet. The only plugin i have is vlc web plugin and stuttering persists whether its on or off.

If Safe Mode didn't change a thing then it's most definitely something that completely kills the advantages you'd have from hardware acceleration, as Safe Mode also disables that.
This means it's likely there's something at the system level interfering with full-screen playback, like a gaming overlay or what not that might not know about Pale Moon (as opposed to other browsers) and as a result not having a rule/exception to configure it the way it needs to.

It appears the in-game overlay from Amd Radeon software was the main issue. As soon as i turned it off the full screen video stuttering disappeared. Thank you for the help.
