When I go to edit->preferences->graphics I checkmark (enable) Basic Shaders and Atmospheric Shaders. I go to different tabs in the preferences, and those stay. But if I push Apply, and then OK, and leave preferences, I see a 'flash' of sorts on the screen, and when I go back to edit->preferences->graphics, the checkmark next to those items is lost. This all works fine in 1.26.4, and the settings in that release work beautifully.
First, the "about" info.....
