Strangely, the ThemePainter issue came up in my thread about gentoo
and disappearing menus.  I had tried ThemePainter but stupid me, I
only tried ThemePainter=qt by itself. It didn't work. And my problem
went away later. Yesterday my disappearing menus disappeared again. So
I tried the ThemePainter trick again. But with the twist suggested
here and in the linked to thread. First I fired up mythfrontend w/ -O
ThemePainter=OpenGL. Then I killed it and fired up mythfrontend w/ -O
ThemePainter=qt. The menus reappeared! Note that my frontend has
always repored that qt is the theme painter. Every time it was launch
except when OpenGL was forced. But still this trick worked. There is
something subtle going on back there.
