This happens to me with svn 4227 and I think all versions since colorpicking was made working correctly. I did not report it, because the flickering was very short and not very obvious and I first just thought its bad luck and always was there adn only happens in beginning of game. But yesterday me and my son saw this problems very obvious in a network game and he told me that he also saw this but was not sure if it was there or not first. ( but this happens in single player games too ).
for the flickering:
This happens with standard selection enabled ( select buf ) especailly in the beginning of the game. Just select units and move the camera a bit around. Especially in the beginning you suddenly have one (render)frame which is completly dark( at least it looks like this ). We both use nvidia cards ( geforce 650 TI )with ubuntu 12.04 .
- this does not happen in 3.7.1
- it looks like it slows down the rendering if it happens ( not sure about that, as its not very obvious )
for color picking
The above was the reason I switched on colorpicking to see the difference. Indeed the above problem was not there anymore so I played a full game 1on1 vs CPU. In the end of the game I noticed some small freezes every time I selected the units. In the end I had round about 150 units and I opened up a selection square to select my fighters all over the screen. something like 40 fighters were in the selection range. This gave me freezes form up to 0.5 seconds just to select the units and was very obvious :-/ .
( I thought these two things might be related, thats why I put them in the same post. If it turns out that these are different issues, we should split the topic )
Update: Colorpicking is fixed
