Description loftar 2014-03-14 08:16:52 CET

Clicktests depend on colors coming out of the framebuffer exactly the way they were drawn, which does not always seem to be the case, depending on environment and system configuration. It would be good if a more stable solution could be implemented, such as using an FBO for producing the clicktest image rather than the window-system framebuffer.

The problem appears to be more common on OSX, for some reason.

Comment 2 loftar 2014-03-14 08:18:34 CET

One reliable way to reproduce the problem is to have the system graphics configuration set to 16-bit color depth, since that will guarantee the colors to be distorted. It can currently be said, therefore, that the client requires 32-bit colors.

(But who uses 16-bit colors in this day and age anyway?)
