the next version of the the underlying component called GTK is now with us. Its called GTK-4. You will begin to see applications being built with this version of GTK.
What this means is that if you are using any themes (stylesheets in GNOME parlance) the apps will look very different from your current theme.
All GTK based themes in the future will need to be updated to support GTK-4.
The vast majority of GTK themes now available will not support GTK-4 immediately - and probably - will never be updated where some budding dev has dashed off a stylised version of an existing theme.
Those apps using GTK-4 will default to the Adwaita based theme.
Right now the only GTK-4 compatible themes that I’m aware of is Yaru, Adwaita and Plata. There may be others - please let me know.
Our default theme is called Pocillo - that does not have GTK-4 support (yet). Others in “Themes & Layouts” also may never be updated.
So what should be done. Well that’s the reason for raising this topic.
We could for instance “scrap” our default theme - and just use Yaru. Big disadvantage - Yaru has no Budgie support - also Adwaita does not have Budgie support.
We could use Plata … personal opinion - I don’t think it looks great (too dark).
We could put in the effort to add Budgie support to Yaru - shouldnt be too difficult. Disadvantage - we are using the default Ubuntu theme so it may cause confusion with our identify.
We could put the effort to reskin Yaru with Pocillo colours. Disadvantage - Yaru only comes in dark and normal variants - Pocillo has 6 different variants. Plus we need to regularly rebase the theme as Yaru is changed … we really need a dedicated new team member to make this happen.
We could spend effort to add GTK-4 capabilities to Pocillo - we really need a dedicated new team member to make this happen.
