thank you so much for the reply. Yes, I’m using the latest version of chrome - Version 61.0.3163.100 (Offizieller Build) (64-Bit).
Besides, the graphics card driver, google chrome and **Firefox **have been updated to the latest release.
I searched the solution for a long time. Actually, I just found out something really interesting.
I use a Windows 7 OS with AMD graphic card FirePro 5000. ,
In google chrome:
WEBG_depth_texture is not in the webgl report list
pickPositionSupported is still FALSE.
WEBG_depth_texture is in the webgl report list
pickPositionSupported is still TRUE.
But pickPosition always returns the false value (not where I clicked/hovered)
Today I have installed Ubuntu 16.04 through VirtualBox on my Windows 7. Everything worked fine with both the Google Chrome and Firefox in Ubuntu!
Before I install Ubuntu on my computer I was pretty sure my problem was hardware-related.
But now I really don’t know if this OS-related?? Maybe the compatibility of WebGL support in windows 7 with AMD FirePro 5000 is not as good as Ubuntu?
Have you or any member of your team had such problem before?
