Use `backdrop-filter` over `filter` for background

[SudoVanilla]

With filter, the framerate seems to drop when the background is changing: https://cdn.korbsstudio.com/2022-01-15%2019-36-56.mp4 (Dead link)

With backdrop-filter, seems more smooth with no frame drop: https://cdn.korbsstudio.com/2022-01-15-19-35-58.mp4 (Dead link)

Usually adding something basic to CSS should help, kinda like:

.background::before {
     position: fixed;
     top: 0px;
     left: 0px;
     width: 100%;
     height: 100%;
     backdrop-filter: blur(64px) brightness(50%) saturate(150%);
}

I need more information on this. Switching filter (current element) with backdrop-filter (everything below this element) seems like a counterintuitive method to "optimize stuff"; this, plus I never actually had any slowdowns in any of my browsers and machines, so I am much more inclined to believe that hardware acceleration is not really working well on your setup.

Can you please share your setup? Linux distro details, Sunamu version (including the package type -- AppImage, AUR, etc.), and a bit of your hardware info.

Of course, Windows related issues are unsupported at this moment even if they merely relate to performance.

Hardware

• Intel Core i3-7100U
• 8GB DDR4
• Intel HD 620

Software

• Ubuntu 21.04 and elementary OS(so basically just Ubuntu)
• DEs: MATE, KDE, XFCE, LXDE, and Pantheon

Other Information

• Package type used was AppImage
• Sunamu version: 1.3.1

I was switching between DEs and distros at the time on a spare machine of mine, runs pretty smooth on Pantheon, which is surprising since Pantheon can be heavy by itself. As for LXDE, that DE alone was too laggy on it's own. I'm currently converting this machine into a dashboard with Sunamu running on a secondary monitor.

Could you try to run Sunamu "as natively as possible" eg. via DEB or straight from (tagged v1.3.1) source?

Yeah, did some digging, seems the computer has issues with hardware acceleration nowadays. Back then it handled a lot just fine as it was my primary machine. I think I'll close the issue then, but backdrop-fitler did act smoother for me with bad hardware acceleration.

There it is! RIP AppImage :C

Yeah........ let's just not go ahead of ourselves here... Closing for now.
