Strange 3D View Corruption Due to Graphics Drivers Maybe?

jd2adams

Hey Global Mapper Community:

It has been about three months since I looked at lidar data in 3D View on my laptop and something is not right today. Please see the inserted screen grabs.

3D View is corrupted with what appears to be tiles in the wrong places and some sort of strut structures in places.

I have a Dell 7680 Precision laptop with NVIDIA RTX 2000 Ada GPU.

I did update drivers this weekend installing Intel gfx_win_101.6734 from Dell's driver download site and NVIDIA driver 572.83 Production Branch from NVIDIA's site.

Anyone have thoughts I should do?

I am heading to Intel's site now and check for an update UHD driver.

Sorry for posting this in Announcements and New. Can someone move this Technical Support?

Thank You.

Hello,

Can you forward this on to Global Mapper support at geohelp@bluemarblegeo.com ?

Also, assuming you are licensed for it, can you install Global Mapper 26.1 and see if that has the same issue?

Thanks,

Hi Mike. Thank you.

Sorry I should have elaborated ... what triggered this was I had just installed 26.1.2 b041525 and preparing for field work this week at Saratoga National Historical Park when I noticed this problem. So yes the problem is the same in 26.1.2 b041525. I still had 26.0.2 b121824 installed and found the problem in that older version also.

I will send this to GM support later tonight.

Thanks for the additional information. Since the problem just appeared in older GM (26.0.2) and the latest (26.1.2), it does sound like the video driver update is likely the cause.

If you can send a sample file that shows the issue to geohelp@bluemarblegeo.com our 3D developers might have some idea of what might cause a display like that.

Thanks,

I'm experiencing the same thing in the newest release. Seems to be zoom level dependent. Screen record/gamebar isn't working for me, but here's a few screenshots as I zoom in
