[Chimera-users] Dim colors in Chimera on OS X 10.10 public beta (Yosemite)

[Jaime Stark]

I was seeing this problem too in Yosemite. It’s easily fixed by turning on the “Debug OpenGL on startup” as Conrad suggests. When you next start Chimera, in the OpenGL options that popup, disable DrawElementsInstanced. That will fix the dim coloring for small molecules on Yosemite for now.

The next time you start Chimera, it should display a dialog where you can selectively turn certain OpenGL options on and off (see http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/debug/debug.html).  If you discover anything, please let us know.
