1. When you colonize a new planet, on the Colonizing Event screen, an old picture from the previous Colonizing Event screen appears for a split second before it changes to the new correct one.
I have seen this too.
What i think is the problem is that it is a direct-x buffer usage problem. Direct-x normally work with a front- and one or more back-buffers. In one you draw something and the other one is shown.
Normally the sequence is like: you draw something in a back buffer, you switch the buffers (the back buffer becomes the front buffer, and the front buffer becomes a back buffer), you show the (front) buffer.
What appears to happen here is: They show the buffer (the front buffer still contains the image of the last time this buffer was used), they update the image in the back buffer, they switch the buffer (now you see the new colonization image). The faster your system the shorter the flash of the old image will be.
If my hypothesis is correct then the fix will be trivial.
