Did rectangle zoom it work for you before the change?
Actually I am seeing a lot of problems when using hardware accelerated
OpenGL, (on intel graphics cards) but when using software rendering
(e.g. using a remote X-session) I think all is well. you can tell what
OpenGL renderer you are using by:
glxinfo | grep renderer
I will try to debug these problems, but I'm not sure how ...
Did rectangle zoom it work for you before the change? Maybe this will
give me a clue as to debugging.
