Dear Dev,

I have installed version 2.0.4 on WinXP and I noticed already a strange
flickering in the buttons which I created with a macro. It is very easy to
reproduce this behaviour: just create a dialog, add a couple of oversized
buttons with some light background colour, then execute the dialog. You will
see that the buttons flicker quite heavily. I reported this as a bug
already.

Recently however I was using OOo Writer with a beamer (projector) and I
noticed that whenever winXP was refreshing the windows (even simply because
of a mouse movement, or by opening a new window, or switching to another
application...) the beamer was losing the synch and the image flickered or
disappeared completely. The maximum refresh rate of the projector was 60Hz.
I have reverted to OOo 2.0.3 and the problem disappeared so I can rule out a
problem with the projector.
So my question: was there a major change in the way windows are invalidated
and refreshed between OOo 2.0.3 and OOo 2.0.4? Has this something to do with
the new functionality enabling impress presentations to be projected on a
secondary monitor? I would like to file a bug report, but I don't want to
waste the precious time of the developers.

Regards,

Michele Zarri
