https://github.com/SFML/SFML/commit/561eb82f14e77f3c9b9e6bd50e59971eef1e9bdaThis commit I believe is causing a problem. Running my program, the window will fade to black & white in Ubuntu if you idle for a few seconds. The 8/4 commit prior does not have this problem.
I cannot provide a code example, but I'm certain you can easily replicate it.
Here's a shot of my desktop w/ the fade problem (8/12 commit build).
And here's what the window is supposed to look like (8/4 commit build).
Some background:
* I request focus post window creation, so requesting focus does nothing.
* When I click in the window, it does not fade back in. It remains black & white regardless. Color never comes back.
* None of my code has changed in between each SFML commit above. What worked before no longer works.
If you need more info, I'll provide what I can.
