I was actually asking @Nexan 
I have the same issue. I did notice that the X Server Settings program lists my driver as 465.31, but pacman -Q --info opencl-nvidia lists 470.42.01-1. Using X11 on the newest Manjaro Stable update with a 1070 Ti. I noticed this issue from Minecraft returning a GLFW error.

glxgears are working like normal. But it looks not all applications are affected.
I confirm this in Firefox. In about:support in the compositor section it says Compositing WebRender (Software) and in about:config it creates the failure IDs gfx.blacklist.webrender.compositor.failureid FEATURE_FAILURE_GLXTEST_FAILED and gfx.blacklist.webrender.failureid FEATURE_FAILURE_GLXTEST_FAILED
Some other application like the flatpak version of the telegram messenger crashes instantly and then after a restart it disables OpenGL with the following message:
I haven’t confirmed this with other applications, but the extremely poor performance is a strong indicator, I would say. For example, if I scroll within the Chromium it feels like it is rendered with 10 FPS instead of 75 as before (my Monitor has a 75 Hz refresh rate). Same in the electron based Visual Studio Code. But other Application like Intellij or most GTK Apps run smooth as before. The desktop itself also runs smoothly, when switching workspaces or moving windows around the animations feels even more fluid than before.
So the title of this thread is maybe a bit misleading. I should rename it too »Some Application can’t access OpenGL (and OpenCL) after Upgrading to Nvidia 470«
x11, I didn’t try Wayland yet (as it is disabled by default).

Same here (with GTX 1070).
Some games I can still launch fine, others will crash, yet others will freeze the entire system (e.g. Valheim, need to kill Steam/the game from another session to resume). Glxgears works, boa (Blades Of Agony, installed via snap) does not.
100% reproducible.
I thought at first the problem was upgrading to the 5.10 kernel (was using 5.4 before), but apparently that’s not it as the problems persist when downgrading back to 5.4.

Also using X11, not Wayland.
Will try downgrading to nvidia 46X to see if that solves it.
Edit: Okay… how do I actually do this? There used to be a list in the Hardware Configuration where you could select the used driver, but it only lists 470 and 390 now. The previous version is apparently gone.
Even after looking into this for over an hour, I can not figure out a way to get the actually working NVIDIA 465 version back.
Why were the old versions deleted?
Why is there no way to easily select the driver version like there used to be?
Apparently, this new “mhwd-nvidia” package replaced all useful packages:
And if there is a way to install mhwd-nvidia-465xx again, I have not been able to find it.
Seriously… why would you do something this harmful and remove all options except the very latest (which is bound to cause trouble for some) and an ancient version?
Its been like that for a while now. Phil has posted a guide (I’ll try and find it) for you to be able to compile your own drivers if the latest nvidia isn’t compatible with your card
Edit here’s the link
Thanks for the link - still, what an abhorrently terrible decision.
I tried following that guide, but it appears that the latest supported version for this is 450. 465 is nowhere to be found. Or rather, it IS found, but doesn’t seem to be open for anyone, it asks me for Gitlab credentials.
Guess I’ll take 450, as it is still better than 390…
I managed to switch back to 450 (and kernel 5.4)… but to my surprise, the problems remain exactly the same.
glxgears runs no problem, so does Loop Hero, so do all (at least all I got installed) games running through Proton.
But Valheim or Blades Of Agony (if you want to test yourself: Install Wolfenstein | Blade of Agony on Linux | Snap Store ) either black-screen or crash on launch…
Which just makes me wonder what is actually the issue here… I am totally out of ideas if it is neither the NVIDIA driver (or 450 just happens to have exactly the same problem as 470, which I find unlikely) nor the kernel (I was on 5.4 for quite a while without any problems).
Also here the update with nowNVIDIA 470.42.01 did break my opencl.
Darktable no longer is able to work with opencl, what really slows down things.
Any hint to get back to a setup with opencl enabled really would be great:

So indeed really something regarding the needed opencl lib (?) has happened.
Any hint is welcome!
Did you try downgrading to 450 using the guide linked above?
Just make sure you are using kernel 5.4 when you do, as 450 will not compile with 5.10…
Would be interesting to see if it fixes the problems for you (didn’t for me).
sigh
Who is ready for some more confusion?
Usually, I use Manjaro + Cinnamon. I used to use KDE Plasma, but had a serious bug that would grind the entire system to a halt sometimes.
Anyway, I still have Plasma installed, so I logged out from Cinnamon, logged back in using Plasma… and now all the applications work.
This is with 450, btw. I wonder everything would still work with 470 on Plasma.
Will edit this post once I tried that…
Edit: Yes, 470 with KDE works just fine for me. Go figure…
While both 450 and 470 do not work when using Cinnamon. I do not have the slightest clue what’s going on there, but I suspect my problem is not related to the one initially talked about in this thread.
Probably some incompatibility between Cinnamon and something that got updated a few days ago…
I am really sorry for making this even more of a mess. 
What Kernel Version are you using for the 470 with KDE?
WIth my above setup (Kernel 5.13.1-3 , KDE Plasma 5.22.3 and NVIDIA 470.42.01) opencl does NOT work for me in darktable (although opencl-nvidia 470.42.01-1 installed)
Okay, I am back to NVIDIA 390 legacy driver with the matching opencl. At least this now seems to work. So looks indeed like NVIDIA again fu**ed up with the recent 470 drivers. … …
If price for grafic cards would not be so insane these days, I would look to ditch my NVIDIA card and check if AMD has suitable options … …
I’m using 5.4 with 470 on KDE now.
Im running cinnamon with the latest nvidia drivers (using prime though as I’m on laptop). I’ll see what I can reproduce, but I’m on testing branch rather than stable
Could be something to do with cinnamon being updated I guess but wouldn’t have thought so
I think Testing is currently on par with Stable.

To be fair, the 470.42.01 driver is considered beta by nvidia… I’m not sure why it was pushed to the stable branch.

This could be relevant: OpenCL compilation fails with `Unresolved extern function '__nv_fast_exp2f'` with drivers 470.42.01 - Linux - NVIDIA Developer Forums
It’s not (EDIT: you probably made a typo, you meant 470 not 472?). Anyway, Manjaro uses the latest for video-nvidia package as far as I know.
Yes, I made a typo, I meant 470.42.01. Still, it’s a beta driver. Even Arch Linux only provides 465.X in its repositories.
