I occasionally get a graphical glitch when using Kira’s Orbital Laser ability. It’s happened a number of times, the most recent probably in the last day or two. I have not been able to identify the conditions necessary to reproduce it consistently; it has occurred on every map at least once and in various conditions.
Known issue? I couldn’t find anything in a quick browse through the forums and a google search, but I didn’t search terribly thoroughly. I saw a vaguely similar issue related to lens flare with Radeon, but I do not have a Radeon card. If any additional info is needed feel free to let me know.
