KB legend background problem! addons work fine though?

Are you running a 64bit system ? KB:TL was never good with those. I was lucky with mine. AP and Crossworlds are newer and specifically built to run mainly on such systems.

Otherwise try a partition with a 32-bit system. XP has by far the least sources of errors with KB:TL.

Try turning off antialiasing and V-Sync and check if the errors still appear.

Get the latest drivers for your hardware (not only video card but also sound chip).

Use Nvidia graphics cards
