World of Warcraft

WoW 3.3.5a mostly works with Proton. but mouse camera movement is borked for all monitors except the primary monitor (camera of chaos). Video: https://www.youtube.com/watch?v=zl-WrmCkNsY

Borked behaviour occurred with Proton-GE, Proton Experimental and Wine-GE so it seems to impact most of the common Wine/Proton variants.

Here are some workaround options, although all of them suck in their own ways, none of them give native behaviour like on Windows.

Gamescope

Works, but you don't get clipboard. The window also can't be dynamically resized under gamescope resulting in incorrect font sizing, letterboxing or pillarboxing.

Gamescope with clipboard

If you want clipboard, pass:

--backend sdl

You also need to run it with this env var:

SDL_VIDEODRIVER=wayland

Unfortunately this causes the OS mouse cursor to be rendered over the top of the regular cursor.

PROTON_ENABLE_WAYLAND

You can force Proton to use Wayland by setting env var:

PROTON_ENABLE_WAYLAND=1

Unfortunately this breaks the window border; you get a Wine-rendered border and the window can't be moved or resized properly. This setting is therefore only useful if you want to play in borderless windowed mode.
