Every time you open the PvP interface window, the games by profession pie chart goes absolutely bonkers spinning out of control. Not only does this look ridiculous, but the graph used to just slightly spread out from a balanced distribution instead of doing a random, full 360 spinout. You can see this exact bug when you open the WvW window; the points per world pie chart goes crazy. What’s weird is that this only seems to happen the first time you open the WvW window each time you start up GW2; open the WvW window again and it’s fine like it used to be. Makes this mess seem like an obvious bug.
Please get your pie charts under control ANet, those graphs are going fast enough to get a ticket and it’s only a matter of time until someone calls the cops :P
