I see, options are:
lower resolution for OpenGL apps
or
bpp 16 for OpenGL apps

Also, as I understand OpenGL can't be turned on while changing physical
resolution by Ctrl-Alt-+/- on the fly ?

Actually I not seen more warnings as in initial post. Something was
fixed not know what exactly, may be fresh -CURRENT helps.
