Yes
Provide extra information to complete the original description of the issue:
Flying around Victorville (KVCV) 34°35′51″N 117°22′59″W, my usual Terrain level of detail setting is 110 and the terrain changes weirdly as I come closer. (Using current MSFS SU9 Beta v1.25.5.0 with Xometry Design KVCV addon)
If relevant, provide additional screenshots/video:
This is the outcome if I change the Terrain level of detail to 10, 110 and 400.
