--- Comment #2 from Simon Spinner <simon.spin...@gmail.com> ---
The nvidia driver (up to 465) does not support querying the texture format of
wayland textures via EGL_TEXTURE_FORMAT. Depending on the texture format Kwin
determines for a window whether it should use an alpha channel or not. If the
query fails, it currently defaults to no alpha channel. For nvidia users it
would be better if it defaults to assume an alpha channel for all windows. This
would help to make transparent windows work better (e.g., latte dock has a
black background for me) and allow for the blur effect.
