Slight stuttering still exists after 1.8.30 update

I found that a fixed stuttering phenomenon appeared in the luxury version of NZQN and ORBX LOWI airports.
High end setting
In addition, orbx loww and lowz have not been tested completely, but in other built-in airports, slight stuttering is extremely rare.
Stuttering occurs at sunrise and sunset, and the overall rendering may be refreshed due to changes in light angles.
There is indeed occasional stuttering. Whether it’s C208 or carenado 182.
