My only issue is that I get these mysterious red blocks (see screenshot below) at the side of any runway I may be taking off/or landing.
Is there is a fix for this?
Thanking you in advance.

I turned off the DX10 preview as advised, and it appears to have resolved the issue, thanks for you prompt reply.george[flytampa] wrote:Turn off DX10 Preview in FSX settings or use Steve's DX10 Fixer or remove the papi.bgl files.
