Phoronix: KDE's KWin Merges Wayland Explicit Sync Support

A day after explicit sync support was merged for XWayland, a week after explicit sync support for Mesa Vulkan drivers hit Mesa 24.1, and GNOME's Mutter enabling explicit sync at the end of March, KDE's KWin compositor has now merged its Wayland explicit sync support!..

For all those who can't wait to use it, there is a backport patch for the 6.0 branch as well: https://invent.kde.org/plasma/kwin/-..._requests/5511

Cool!

do the open source amd and intel gpu drivers utilizeexplicit sync?

The article just mentioned that mesa support for explicit sync hit in Mesa 24.1. The catch is that it's only the Vulkan windowing API that supports it so... afaik Gnome is the only compositor with a shipped Vulkan backend, and they consider it super experimental.

That's not quite right. GTK ships with a Vulkan backend that is recommended by default these days but that doesn't cover all of GNOME. Mostly people don't realize this but GNOME Shell does not use GTK. It has its own toolkit based on Clutter.

Once the matching Xwayland and NVidia driver updates are out, most problems with NVidia on Wayland will be gone.

Once again, FOSS community bends over for ngreedia…

i meant the kernel driver.

It feels like nothingburger for FOSS users. The only benefit is nvidia users will stop shart everytime wayland is mentioned.

Great, now imagine if the Wayland folks listened to Nvidia 10 years and supported superior EGLStreams instead of sticking to shitty GBM. Wayland could’ve taken way less than 16 years to be adopted. Lol
