[Mesa-dev] [Bug 69101] prime: black window

--- Comment #17 from Christoph Haag <haagch.christoph at googlemail.com> ---
Well, some people here talk about PRIME not working with compositing, some
people are talking about PRIME having some issues with OpenGL compositing.

The second one is still an issue and maybe it's some race condition or so,
because some things (almost?) never work, and some things work often, and fail
sometimes.

To summarize: With Xrender Compositing there's no problem, but with OpenGL
compositing there is.

With both compton --backend glx and kwin with opengl compositing I randomly get
the black screen by just starting and quitting DRI_PRIME=1 glxgears a few
times. It works about half the time.

It was already in the kde bugtracker:
https://bugs.kde.org/show_bug.cgi?id=324864
and comment 15 said: "Resizing will recreate and rebind the window texture"
So maybe there is some starting point to investigate why that happens?
