KDE has extension for Google Chrome / Chromium to provide integration with Plasma (and partly XFCE) desktop (Media playback, file downloads, KDE Connect etc). It's called Plasma Browser Integra...
Yeah on TW every time my kernel updated the problem would happen and it would only go away when Vivaldi updated, no Nvidia Driver updates ever fixed it nor did any further kernel fix it either
I hadn't known/remembered CachyOS, so I initially thought it might use an older kernel, but it seems to use roughly the latest kernel version, but with various modifications under the hood
Maybe I should embrace the Flatpak version from now on and see how that goes, if can remember to I can try out the different browsers to see if they have the plasma browser integration problem or not tomorrow after I finish up high school for the day.
Anyways it is getting late and I need to get to bed and thanks so much for your assistance! I'm still new to this immutable distro scene and so far I'm liking it!
