+1 on GNU/Linux (default GTK3).

This looks like GTK or X server issue, so:

0) If possible, update your X server and relevant libraries. If you're
familiar with X server configuration, try to disable some features (e.g.
GLX, DRI and so).

1) Can you try a different X toolkit? If possible, try to rebuild
with '--with-x-toolkit=lucid' or '--with-x-toolkit=none'.

2) Can you try to run Emacs under xtruss
(http://www.chiark.greenend.org.uk/~sgtatham/xtruss) and collect
output?
