Huh but GPUs only support it since like 2016 or 2017. Older ones won’t be able to render GTK4?
As per https://blog.gtk.org/2024/01/28/new-renderers-for-gtk/ and https://www.phoronix.com/news/GTK-4.16-Released :
You can still use either a new OpenGL renderer or the old OpenGL renderer. This can be set with the
GSK_RENDERER
environment variable (e.g.GSK_RENDERER=gl
)I would assume it will also probably detect unsupported hardware and switch to OpenGL automatically but I don’t have any source to back this up.
I hope at least distros will make the switching automated because without it a lot of users will have issues, especially since Ubuntu and Fedora use GNOME by default.
There’s still OpenGL backends, a newer one that shares the same backend as the Vulkan renderer and the old OpenGL renderer.
Wait, UI toolkits need a render backend? Old FLTK too?
Need? No. But hardware acceleration makes things faster and more efficient.
Truat me, you ro not want to experience CPU based rendering on high resolution displays
