I can easily share this point of view. :-)
I just found a workaround so that Security Update 2021-007 Catalina can be installed... minus 'AppleIntelHD4000GraphicsGLDriver.bundle'. :
As already told I have a clean install of Catalina on a second Harddisk. I installed 'Security Update 2021-006 Catalina' onto this HD. This includes "/System/Library/Extensions/AppleIntelHD4000GraphicsGLDriver.bundle" Version 14.7.18
(This is the last working version of this bundle. Update 007 installs version 14.7.20, which is obviously broken)
I copied this bundle (and only this) to my primary System with 'Security Update 2021-007 Catalina' installed.
After a reboot to my primary system everything works again as expected, all WebGL-Pages can be loaded. :-)
This has the advantage that 'Security Update 2021-007 Catalina' is still installed, so there's no annoying reminder to install new updates from the system preferences. And in fact all Security Updates are installed - only with the exception of the GLDriver bundle.
I think that's currently the least possible violation of system security.

Comparing the two systems (clean install and install with security update) the extensions for intel GPU HD4000 are absolutly identical. Same size, same date.
Ok you are right
the size are different
AppleIntelHD4000Graphics.kext
782 541 bytes before update
787120 bytes after update
Hey, do you have any further tips on how to do that?
I am kind of lost here.
Let's hope Apple fix the problem in an upcoming Security Update.
It's a good practice to backup before any system update.
You never know, right?
show me where i repeated myself in that context more than once to the same person. go ahead.

You're welcome :-)
It's not the 90s. A computer without updated security software is not a fully functional computer.
Okay, never mind, we’re done here.
what does that mean?
My MacBook Pro with Intel HD Graphics 4000 1536 MB was manufactured in September 2016. OpenGL and WebGL stopped functioning within 5 years of the manufacture date. This is not OK.

Me too !
Very good point Ray
My Macbookpro 9.2 (mid 2012) was manufactured in october 2016
We deserve a solution from Apple.
Our macs are five years old !
