Constant buffer overflow

Hi. When I leave the game on the background for a longer time and do something else. When I go back to game I often get message window "Constant buffer overflow". It's really not a big problem and doesn't usually happen and I can just start the game again, but I just wanted to let you know.

Same, happens after game runs in background (minimized) for extended period

I have had the exact same issue twice today ... did not notice this happening last week. No change in the amount of time I'm AFK that spawns the error (anywhere from 8 to 25 minutes). Awaiting a fix...
