When I started to try and play Spiral Knights on my Windows, the screen flashes blacks for a few seconds and it closes. It seems that it wants to go full screen but it can't, despite that the last time I played it I'd unchecked the full screen checkbox and applied it.
What are the solutions to this issue?
The most common cause of this problem is graphics drivers that are not fully compatible with Spiral Knights. Please try updating your graphics drivers to see it resolves the problem. If you need help finding information about your graphics card please follow Step 2 in the Technical Help Sticky.
