Linux, GTK2: issue with site https://basilisk-browser.org

[Mark-PM]

Hello,
Not a great issue but strange anyway: coming from the current release announcement (https://forum.palemoon.org/viewtopic.php?f=61&t=31590) i opened the release notes (https://basilisk-browser.org/releasenotes.shtml and observed a very high CPU consumption.
This effect/issue does not concern PaleMoon (on Linux), Basilisk on Windows (nor Roytam's ,fork' - if of any interest).
Thus exclusively Basilisk on Linux (Debian 11 based in this case).
The screenshot was made with the last version (2024.08.11) of Basilisk, to falsify: it's not an issue that came with the new release.
Many thanks for your works on the new relase btw @ Basilisv-Dev.

For me, it gets ~55% of the CPU idle (Linux GTK2, didn’t test with Pale Moon).

I think it’s relate to the background gradient effect: when I scroll down off that background the CPU consumption lowers; and if I just delete that “@keyframes HueRotate {…}” part of the CSS style it lowers too.

If you don't have hardware acceleration then this can be a taxing effect. If it doesn't occur with Pale Moon, then try enabling HWA in Basilisk as well

Thanks for your replies gabrgv and moonchild!

HW acceleration is enabled in the Preferences section; below i added a list of my 'acceleration' entries in 'about:config'.
The GPU is an internal Intel HD 530: 'about:support' tells:

WebGL 1 Driver Version: 4.6 (Compatibility Profile) Mesa 20.3.5
Asynchronous Pan/Zoom: none

Have a nice sunday!
