i've been wondering about this for a while and thought i'd ask here... i have a xps 9370 and am on Ubuntu with i3 as my wm.
my question is about browser (Chromium-based ones in particular) performance. i always heard that performance should be better than on Windows for page rendering but on that laptop rendering on Linux is just particularly slow. fast scrolling shows white space before the content actually showing up. websites like YouTube and Twitch takes more than 3 seconds to render.
in Windows, the same pages load almost instantly. any similar experience? FYI: performance is as crappy in Firefox
i'm wondering if it's because of my 4k display with integrated GPU... the only thing I regret about that laptop...
bonus question: any performance improvement when using a wayland-based WM opposed to xorg-based one?
It depends on several variables. At first, see if VAAPI is enabled and functional.

Chromium's rendering engine has notoriously awful scrolling issues under pretty much all platforms. Smooth scrolling on or not, if you're using a chromium-based browser, you're going to frequently run into jerky scrolling and glitchy rendering while scrolling. I imagine it's much worse on a 4K monitor with an integrated GPU. You can try out forcing chromium to override the software rendering list (in chrome://flags), but it's a potshot. The main reason I and many others have stuck with FF and gecko/servo browsers in general is because of the rendering engine. Fonts are fucking thicc and readable by default (something chromium stuff always struggles with), and scrolling (whether you're using smooth or not), is pretty much perfect under all platforms. FF also allows for text-only zoom, which is amazing on hidpi displays. Chromiumshit still hasn't come close to implementing this.

>VAAPI how do i enable this? this is separate from chromium's hardware acceleration setting right?
seems rather new, never heard about it, can i toggle this via chrome://flags?
Firefox is good for me on windows and linux. Go to about:config and try gfx.webrender.enabled;true gfx.webrender.all;true
Jordan Howard
on windows there's no issues whatsoever, it runs smooth using the same settings and resolution, etc
and firefox runs like shit too :(
Josiah Diaz
also same happens with youtube video playback... mpv is a little better but still sucks in full screen... why would they put such a shitty gpu with such a glorious display argh
Zachary Wright
i'll reinstall firefox; let me test
Jaxon Smith
I've heard disabling smooth scroll has helped for some but I don't have any issues with it on.
Nathan Wilson
firefox just made my fans start up for the first time in a month... wtf performance sucks even more
yeah disabled it right away it was sluggish as hell

What toaster are you running?
Ayden Moore
what does chrome://gpu say? it sounds like no hardware acceleration on linux

must be my fucking 4k display :( that resolution is hard for the integrated gpu to push smoothly damn it
Anthony Nelson
I have my i5 nuc connected to my 4k tv. What are you trying to do in your browser?
James Hernandez
most errors are cleared with the flags only remaining one is:
Well I use ubo and noop domains that I need to work and stream with mpv. I do this on any device. But I was able to load youtube fine.
Brandon Mitchell
thanks again user this helped already so much
Caleb Garcia
That error is not important. I think your main issue has something to do with i3/compositing. Try something else like kwin and see if shit's working fine. If not, you probably have some kind of driver issue.
Carter Sanders
i use compton for compositing i'll try to kill it and see it it helps i will also try another wm just in case i3 is being retarded
Adam Rodriguez
>linux just works Yeah, right.
Jordan Hill
for some reason killing compton seems to improve browser performance even when no opacity is applied :-/ guess I'll btfo compton from my config then
Jaxon Gray
holy fucking shit killing compton and using the flags from that user really improved my config! it's almost better than it is on windows now!
THANKS ALL SO MUCH
Ryan Thomas
>compton why didn't you mention it earlier, compton is buggy pile of trash
Ian Johnson
the more i learn about it the more i discover that it is indeed, a pile of trash. i guess i should've told it first hand hehe
I have the opposite experience completely. I use a chromium-based browser (vivaldi) for casual browsing, but if I actually need to be reading a lot of digital text, I always use firefox, whether I'm on win, lin, or mac. Maybe this is because all my shit is hidpi. Maybe I'm just too autistic about font rendering. Or maybe it's because I use a lot of different fonts for multilingual stuff, but gecko does not make my eyes bleed, and chromium's rendering definitely does.
Sebastian Butler
All accelerated desktop crap is trash. Use plain fucking Xorg with no goddamn acceleration on GNU/Linux. Compton/Plasma accelerated/Wayland/other bullshit is fucking garbage.
Christian Brooks
wayland is better than xorg though
Jeremiah Fisher
why so?
Justin King
red hat uses it by default so it's good
Evan Collins
It's not a monolithic piece of overgrown trash with features that 99% of the user base doesn't use.
