Wine Wayland Driver Lands Alpha Modifier Support For Opacity Handling

The Wine Wayland driver continues to be improved upon for bettering the experience around Windows games/applications running natively on Wayland Linux desktops without having to go through X11/XWayland. The newest feature merged is alpha modifier support for opacity handling of surfaces.

JiangYi Chen and Rémi Bernon authored support in the Wine Wayland driver for the alpha-modifier-v1 protocol. Wayland's alpha-modifier-v1 protocol allows for specifying an opacity multiplier that the compositor then applies to the window surface during rendering such as for fading and other background effects and more. This now-merged Wine code builds on earlier code posted last month.

This alpha-modifier-v1 support for winewayland.drv was merged yesterday to Git. In turn this new functionality will be part of the Wine 11.11 bi-weekly development release due out later today.

Hopefully by the Wine 12.0 stable release due out in early 2027, the Wine Wayland driver will ideally be in robust shape.
