I'm unable to reproduce this on my system on either the default LL release viewer Second Life Release 6.2.0.526190 (64bit)
or on the EEP-RC viewer: Second Life Release 6.2.0.526104 (64bit)
I tested at the location shown in the attached images - http://maps.secondlife.com/secondlife/NMC%20Campus/130/90/23

I wonder if this is a shader bug in the EEP-RC that affects systems using OpenGL Version: 3.3.0 though.

JETalbot, you are currently using the EEP-RC viewer from http://wiki.secondlife.com/wiki/Linden_Lab_Official:Alternate_Viewers
Can you remember if this problem started when you had a viewer update?

If you install the default LL viewer from https://secondlife.com/support/downloads/, does that fix the problem?
Please don't disappear if this viewer does fix your problem, it may be a bug in EEP that needs investigation.

Thanks :)

My system into:

Hi JETalbot Bookmite,

I can see that you have gone back to the release viewer and have logged in today. I hope all is well now. Please note that EEP based viewer will eventually be promoted to default release and unless we solve your report independently, this issue could affect you again in the future.

If you are inclined to help us test a few things out, please update your Nvidia Geforce drivers to the latest version for your GTX 260 from:
https://www.nvidia.com/Download/driverResults.aspx/112598/en-us

The reinstall the EEP viewer and see if the problem persists.
http://wiki.secondlife.com/wiki/Release_Notes/Second_Life_Release/6.2.0.526104

Please let us know if that works, or if not, and press the Info Provided button.

Thanks!

I did not notice this occurring on any previous update. However, it's been quite some time since I clicked "Default". In normal usage, to minimize lag, I have to keep the settings very low. So this could have slipped in in the previous update (or two), and I might not have noticed.

As you requested, I installed the standard viewer, and tried again.  This time, I was unable to reproduce the problem.

I do want to help, so I have downloaded drivers and the EEP viewer as you suggested.  I will comment again after I have tried them out.

As it turns out, I already have Nvidia's latest driver (v342.01) installed.  It seems that there is nothing further for me to do to help you.

So just to clarify, you can't reproduce this problem on the default release viewer from https://secondlife.com/support/downloads/, but you can reproduce it on the EEP viewer from http://wiki.secondlife.com/wiki/Release_Notes/Second_Life_Release/6.2.0.526104?

JETalbot Bookmite commented at 2019-04-24T23:17:33Z

That is correct, Whirly.  

I reproduced it on the EEP viewer from http://wiki.secondlife.com/wiki/Release_Notes/Second_Life_Release/6.2.0.526104

Then I tried the default release viewer from https://secondlife.com/support/downloads/, but was unable to reproduce the problem.

Then, when asked to upgrade my display driver, I found it was already up-to-date, and had been for a very long time. 

Subsequent steps were also requested, to test operation of both viewers against the "new" driver.  These tests look entirely redundant to me, since the "old" driver IS the "new" driver.
