Pit sign stuck on screen

[Hoksu]

After I started using CSP and Sol, this has happened to me a few times. Not in every race, but it's very annoying when it does. The PIT sign will remain on the screen outside pits, it will be there regardless of camera. I am using preview140 and latest Sol installed manually.

Also what has happened is that after watching replay, the headlights of cars seen on replay will remain on the screen after closing replay.

Any ideas how to fix this problem? Ending game session and starting a new one makes it go away, but it's very annoying having to quit a race weekend after qualifying and then start again hoping it won't re-appear.
