The isos with Cosmic alpha are now downloadable from system76's site!

Fixed a bug that caused widespread crashing with Xwayland games.
Fixed a race condition involving modeset ownership which could lead to flip event timeout errors when enabling the 'fbdev' kernel module parameter in nvidia-drm.
Fixed a regression that caused nvidia-powerd to exit when nvidia-dbus.conf was not present in the /etc/dbus-1/system.d/ directory.
Fixed a bug that could cause memory corruption while handling ACPI events on some notebooks.
Fixed a bug that could cause external displays to become frozen until the next modeset when using PRIME Display Offloading with the NVIDIA dGPU acting as the display offload sink.

Suojellaan suojelualueet – Lakialoite luonnonsuojelualueiden rauhoittamiseksi kaivostoiminnalta

Friday's release of Wine 8.22 is expected to be the last bi-weekly feature release before shifting focus to the code freeze and making Wine 9.0 ready for release in early 2024. It's coming down to the finish line how much more Wine Wayland driver functionality will be merged in time.

A few days ago Wine Wayland's Vulkan support evolved into a usable state while today "part 11" of the Wine Wayland enablement was merged. This 11th set of Wine Wayland driver patches is for mouselook support, including wiring up ClipCursor and relative motion events. The relative mouse cursor support in particular is important for first person shooters and other games.

More details on this latest Wine Wayland code to be merged upstream can be found via this MR. As with the other Wine Wayland work, it's being carried out by Collabora's Alexandros Frantzis.

Opened today is also another merge request for the Wine Wayland driver with that change-set intended to apply surface configuration during Vulkan presentation. This fixes some games running that they resize the area as they become full-screen.

WINE The third and final part of the Vulkan enablement code for allowing Vulkan API graphics use within the Wine Wayland driver has been merged to Wine Git.

There's been Vulkan support being worked on for Wine Wayland that was split into three sets of patches. The final portion of this work by Collabora's Alexandros Frantzis has now been merged -- meaning Vulkan use by Windows software (or going Direct3D to Vulkan) running on Linux within a Wayland native environment is now do-able.

However, mouse not all games will be working properly yet until additional mouse functionality is implemented:

"With this MR you can start enjoying some of your games with the Wayland driver (either directly with Vulkan or with a D3D->Vulkan translation). Please note, however, that we don't currently support what's needed for mouselook (you will currently get erratic view movement), so most first-person 3D games are not playable yet."

See the merge for more details. With the Wine 9.0 feature freeze quickly approaching it remains to be seen if any more of the Wine Wayland code will make it in time for this next stable Wine release due out in early 2024.
