OpenGL (and OpenCL) not working anymore after Ugrading to Nvidia 470.42.01

Yes, it also fixed the crashing of telegram for me and the very poor performance of other apps. Firefox shows now the WebRender without that »(Software)« addition.
But scrolling in most apps contains still some choppy behavior that wasn’t there before, but maybe this is another issue or a wrong Xorg conf or something like that.

You mean you have tearing when scrolling down? Reconfigure your monitor in Nvidia maybe?

No, it’s not tearing. It feels more like micro stuttering. If I activate the visual API indicator on OpenGL in Nvidia Settings, it shows the FPS in apps like Firefox. Then it drops to low single digits for less than a second and then goes back up to 75. This occurs regularly, about every two or three seconds. Looks like something is interrupting the graphic card/driver/compositor/whatever every X seconds. But this behavior wasn’t there before.
Sure, this isn’t a major problem, but it’s annoying when a graphics card that can render games in 4K can’t render a 2D surface smoothly.

Sorry but Darktable with nvidia 470 and opencl still NOT working. 470 is beta and the last official driver on the nvidia page ist 465. Sorry guys, but that sucks a lot.

Yesterday’s updates seems to fix the matter, both Nvidia driver (470.57.02) and Darktable (3.6.0-2) was updated, but the fix come probably from Nvidia, the fix from Darktable side was supposed to come with 3.6.1

Thanks!! Will test it asap.

Works now. Thx all
