Those are essentially bug 22922 / bug 23048. Making them go away would require
some tests to see what is supposed to happen when the applications sets NAN as
point size.

Those messages have nothing to do with shader compilation though, which is what
this bug claims to be about.

Sure, that is a bug, but it isnt the bug which slows things down to 2 fps.
If you actually look at traces, you would notice that the two calls that take
the most amount of cpu time in between each flip are directly related to
compiling and linking a shader program.

Please do some research before commenting. Just reading logs is not enough.
