blackout from 32bit -> 16bit

i run my app in 32bpp, during runtime when i try to snap to 16bpp the window turns and stays black… this happens the other way around too from 16 to 32… this only happens when i try to change colordepth and not for resolution switches. is this my driver or am i doing something wrong?

using detonator 6.50

Are you destroying the GL window instance and then re-creating it with the new color depth? If you are you lost all your textures in the process. You have to reload all the textures at re-creation of a GL window.

At least that’s the only way I know of .
