bug(linux): AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer

[alkaris2]

Describe the bug

When trying to access Downloads for Keyman, I get the following error on loop;

AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer

As as result of this you are unable to access the Downloads page for keymaps from within the app. However after a bit of digging around on the Internet this is easily fixed by setting WEBKIT_DISABLE_DMABUF_RENDERER=1 into the environment.

If you have NVIDIA GPU this is apparently an issue. You could probably just completely disable the WebKit DMABUF Renderer from Keyman to remedy this issue completely.
