As described in my previous post [url=https://www.bungie.net/en/Forum/Post/255314101/0/0]here[/url] I have a graphical corruption issue during explosions. I already did a full reinstall of the game to fix a separate stability issue (which wasn't effective) and this graphical issue also persists. Having seen the corruption a lot, the best I can tell is that the issue is related to the use of a solar weapon or ability. When breaking a solar shield, solar rocket, the texture change in the plume from bright explosion to dark and sparks creates the issue. Hopefully that helps track it down. Not sure what to do at this point.
