I suppose, this is a problem of the installed screen-font.
I also suppose, you use the "instant-preview", that replaces the math inset
with a LaTeX rendering when not editing it.
Are the \Omegas the only affected letters or does this affect all the Greek
symbols?
Are you able to see Greek letters in other editors?

It seems you use a keymap with "dead keys". This is usually not a
LyX-specific, but a system wide setting.
If you like it (generally), you may just keep it and remember to press the
accents *twice* for literal insertion or passing on to the math-editor:
press x ^ ^ i
to get x^{i}
If you don't like it, use a different keymap, either globally or for LyX
(unfortunately, I don't know how to select the keymap under OSX).
