When I first start the editor, this doesn’t happen. After about 5 minutes of use, this happens and persists until I restart. Using 4.7.3

Hi ,

Unfortunately I have not been able to reproduce this on my end. Can you post your dxdiag here so I can take a look? Additionally, about how many BSPs do you typically have in your level before this starts to occur?

Hi ,
