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.

This works around a problem in webkit2gtk where the download dialog
sometimes only renders a blank screen. Setting the environment variable
seems to help, not only in the cases that the issue describes (with a
NVidia graphics card), but also in my testing in a VM.
Fixes: #12587
