Hi Ken:
Before I post the screenshots of what I see after launching your *
.FLTs linked above to illustrate how they they appear the same as yours, since the issue you seem most concerned about is the intermittent display of your custom G-Poly relative to FSDTs G-Poly of the parking lot surface under the new terminal area,
please also provide a *.FLT for the top-down view shown in Post #25 and #52 immediately above using the FinneyGround Crosshairs_Plus aircraft.
This would ensure that I have the exact same parameters applicable on my FS installation as you do when the 'flickering' and 'jagged edge' anomaly appears.
My reply should then properly consist of (5) screenshots to compare with those you have attached / linked to above ...showing the area of the anomaly.
NOTE: Please put the
*.FLT file for the top-down view shown in Post #25 and #52 immediately above using the FinneyGround Crosshairs_Plus aircraft into a ZIP, and attach it directly to this thread at FSDEV so we can again test whether MalwareBytes BrowserGuard FireFox Extension throws another security alert.
If it does, I will request that you once again link to your intended download at a remote site such as DropBox, Google Drive, MS OneDrive, MediaFire etc..
Additionally we must identify whether the anomaly is
only seen when IS3 is actually loading / moving your G-Poly, instead of when loaded by FS itself.
FYI: If, after created / edited by IS3, the BGL which places your G-Poly has been
relocated into a new folder chain physically separate and distinct from the original folder chain where it was last located curing creation / editing, and after re-starting FS, that BGL is loaded
directly by FS using DirectX.
Otherwise, your G-Poly is instead being loaded
indirectly by IS3 ...which is / displaying the G-Poly using OpenGL.
