I am experimenting with integrating the hamster graphics library into an XO activity. <a href="http://github.com/tbaugis/hamster_experiments/wiki" target="_blank">http://github.com/tbaugis/hamster_experiments/wiki</a> ( found on the pycairo resources page: <a href="http://cairographics.org/pycairo/resources/" target="_blank">http://cairographics.org/pycairo/resources/</a> ) Because of the ease with which animation can be rendered with this library, I think it might help some developers to create engaging activities. Unfortunately, I have encountered a problem when I run a very basic test activity on an XO1-5: the mouse pointer flickers whenever a sprite is animated. (This bug also happens when I run the code in fedora desktop on the XO... but does not happen in the sugar emulator or on my f13 box). Here is a video which demonstrates the flickering: <div><a href="http://www.youtube.com/watch?v=jkBTafiwf38">http://www.youtube.com/watch?v=jkBTafiwf38</a> <div> </div><div>Here is the test activity if you'd like to see the behaviour and reference the source: <a href="http://alumni.media.mit.edu/~erikb/tmp/Test.activity.xo" target="_blank">http://alumni.media.mit.edu/~erikb/tmp/Test.activity.xo</a> I am hoping that the sugar community might know of issues which might be responsible for mouse flickering? Thanks. Erik </div></div>
