Switching video to full screen is slow

Komposten

@Pathduck YouTube introduced the option to scroll down to the comments while in fullscreen a while ago (can't remember when, but sometime last year). When you scroll down the search bar appears at the top, so this might be where the search bar comes from when going fullscreen.

Both the embedded YouTube video and Vimeo also goes fullscreen in a stepped fashion for me, but much faster than on YouTube. Vimeo is clearly the winner, with the stepping being so fast it almost isn't there.

For whats it's worth, the transition and redraw of the window while switching from/to fullscreen got drastically slow and noticeable also in my Windows7 32bit since Vivaldi 3.0, noticeable on both Youtube and Twitch. I don't consider it a biggie for me since I don't need to switch many times, once in full screen it remains so until I finished watching.

You are not the only one. There are a bunch of topics and user reports about this:

when I select fullscreen mode on YouTube in Vivaldi it becomes larger in steps takes about 3 seconds. It works fine with Vimeo. YouTube normal-fullscreen transition works good in chrome on my computer. I was having the same problem in Ubuntu.

Pesala

@hackasaur It is a known issue.

Hi, I have the same on Chrome on Linux but more 0.5 seconds for the 3 steps.
Cant check on Windows at moment.

Cheers, mib

As Pesala pointed out, others have this issue too and there doesn't seem to be a fix yet. Some related topics:

I can't recall whether this was properly submitted as a bug yet and if the devs are aware of it.

Here is what it often looks like for me, especially exiting full screen is laggy: https://pictshare.net/m9duau.mp4. It can also become worse (more laggy, slower) than this.

It doesn't even seem to be directly about the video going full screen, but rather about Vivaldi's full screen mode (which is part of the process when making a video go full screen), because the same kind of lag happens when I'm activating just that view (default: F11) on sites like YouTube, Twitch or Vimeo (without making the video full screen). This video shows it: https://pictshare.net/10r68p.mp4.

Once Vivaldi is in full screen mode like this, switching the video to full screen does not lag anymore, then it's just one step. That's what it should always look and feel like.

Vivaldi version: Vivaldi 3.0.1874.38 (Stable channel) (64-bit)
OS: Windows 10 OS Version 1909 (Build 18363.836)

Hi, as I mention in my post it is the same on Chrome and Edge(ium), Edge need two steps, on Windows 10 Pro 2004 (was the same on 1909).
I have no time to search in the Chromium bug tracker but I guess there are reports, too.

Don't even need to go fullscreen, open a panel and the page resizing "redrawing" is laggy, then close it, it has a laggy animation again, every time. It also happens when you open the Ctrl+F (find in page) bar, a laggy experience overall.

My conclusion is YouTube pages must be very heavy for the engine to redraw in different resolutions in real time like this.
Firefox transition "cheats" by fading the screen (does it even redraw the page like this behind the scenes if one manages to disable the fading?).

And yeah it's the same on Chromium, so it's doubly Google's fault.

@mib2berlin
Thanks for pointing that out, I read before that it could be a general Chrome/Chromium issue, so hopefully it'll be fixed at some point.
Some user reports are contradictory though, they only seem to experience the lag in Vivaldi, or at least not as severe in other browsers.

@rluik
You're right, it's the same with opening and closing panels. I just forgot about it because I'm using floating panels where this doesn't happen. Basically toggling any of Vivaldi's UI elements can cause lag on YouTube (Twitch, Vimeo, etc.).

I wouldn't really say Firefox is cheating though, because the fading transition obviously only happens when making the video go full screen. But setting Firefox itself to full screen (also F11) or opening any sidebar is also lag-free in Firefox.

This is embarrassing and needs to be dealt with.
I was going to give Vivaldi another shot, but still not this time.
It's terrible that they ignore such basic usability stuff.
If your graphical stack sucks so much, putting a powerful CPU and GPU to the knees, then why would even consider packing your UI with a ton of animations that doesn't work??!

It seems like Vivaldi is being created as a proof of concept, but not as a usable thing.
Goodbye Vivaldi for another 2 years.

This old problem is very annoying. I hope to see it fixed someday

I wrote about this kind of problem some time ago https://forum.vivaldi.net/topic/40969/very-non-smooth-youtube-page-window-scaling. I don't think it's Vivaldi's full screen mode problem because in my case scaling and going full screen is pretty smooth on twitch or vimeo unlike YT.

Julivex91

Same problem for me.
Full screen(F11) lags everywhere, not youtube or other online video only.

I got so sick of this YouTube fullscreen toggle lag that I spent a night devising a fix, and created a Chrome extension / Tampermonkey script for it:

https://github.com/ZimbiX/youtube-fast-fullscreen-toggle

This thread is the first Google search result for 'youtube fullscreen slow' which still permits replies, so thanks for indulging me despite it not being built for Vivaldi. I have yet to look into making Vivaldi extensions, and I don't know about the Vivaldi performance issue, but this should at least solve the problem with Chrome. And the script may still help on Vivaldi too - let me know

@ZimbiX said in YouTube normal to fullscreen transition lags, becomes larger in steps:

Not working for me using Tampermonkey, I'll wait for Chrome Web Store extension version. Maybe because I've got only 1 sec lag, but it's still worse than in Firefox.

ZimbiX

@Gregor That's a shame it's not working for you. The original version of the extension's been approved on the Chrome Web Store now, but I have tonight managed to improve it further to bring the performance in Chrome close to what it is in Firefox - near instant. Let me know if you have better luck with either the new script in Tampermonkey, or the Chrome Web Store version.

Gregor

Still not working (both versions), but maybe it's on my side (Win7, fullhd). I do not know what affects it.

ZimbiX

Damn. I'll have to do some more testing on other machines

ZimbiX

Ok, I've finally actually tested it in Vivaldi - bug filed here
