Phoronix: GTK4 Now Allows More Efficient Usage With Its Vulkan Renderer

This week the GTK 4.0 development code picked up support for making use of the VK_KHR_incremental_present extension with its Vulkan renderer in order to allow much more efficient behavior...

I'm looking forward to GTK4

Good news for mobile. Eventually Purism phones will move to GTK4. This is the only phone provider smart and brave enough to work on a truly free phone product with software and hardware tightly integrated.

Does the Purism phone support Vulkan? Probably not.

This is unrelated to Wayland? Or does this mean a Wayland compositor that uses Vulkan? Or it's just something GTK4 does irrespective of the compositor and X11/Wayland, like a game rendering with Vulkan?

The spec sheet says that Purism has a Vivante GPU. There is currently no Vulkan driver for Vivante in mesa.

The hardware can, but there is no driver. Just like Purism's specs also say "OpenGL/ES 3.1" when there is only OpenGL 2 currently. Likewise, no OpenCL driver either.

GTK4 applications can use Vulkan to render, this is an optimization for that renderer.

Ok, so on Wayland you'd still have EGL handling the compositing and window management? GTK windows/viewports would just be rendering their content with Vulkan like a windowed game that supports Vulkan?

I know, but I don't think anybody here expect it to stay this way by the time Gnome software stack start migrate to GTK4.
