I have a Nvidia GPU [GeForce GTX 970]and have installed the proprietary driver. It work fairly well (shows video nice), but I have instances where the screen does not update properly and the screen blinks once. This can happen several times, some days it’s more stable. This is quite irritating. The updating shows Firefox with only the title bar and borders. It should not be like this. I think the driver is installed properly, but I am not sure. I thought this could be related to settings.
How old is this 15.3 installation? Which DE do you use? Did it ever work as expected? Does it do the same if you run a different DE session type? Was everything fine running whatever OS it had before 15.3?
Please run inxi -U, then provide input/output within code tags from inxi -F --nvidia run from an X terminal.
I installed 15.3 in April this year. I had to change the motherboard. With 15.2 on my old setup the card functioned rather well. I followed the instructions on https://en.opensuse.org/SDB:NVIDIA_drivers, and i have had this card in my machine since 2018.
The rest of output from inxi is about audio, drives, network etc. Do you need that as well? I don’t under stand what you mean: Does it do the same if you run a different DE session type?
Sometimes it’s because of unstable connection of the graphic card or the cable connection (HDMI/DVI)
I had worse than that, one of my monitor just go to sleep cause of bad HDMI connection the monitor’s HDMI slot has
dust, it works perfectly after I cleaned it.
This shows you have a Maxwell that should be supported by NVidia’s 515 driver, but you are running it on a 470 driver.
There might not be a driver solution. Try logging into some session type other than Plasma, to see whether the problem remains or not without Plasma involvement.
I logged into Gnome, but the result was lagging when loading web pages. I did’nt see any blinking but the result in Gnome was bad, and I did not see any point checking any more. Before I installed the Nvidia driver (April), the web pages was lagging. Does this indicate that the card maybe is to old? Should the Nouveau driver be sufficent for reading the web and see videos?
Gnome Wayland, or Gnome Xorg? All web pages, or only a select few? Please provide examples if only few.

Does this web page lagging occur only in Firefox, or all web browsers? Web browsers should work acceptably with the standard FOSS drivers in standard 15.3 repos. Your card is not nearly too old for web browsing. It has years of life left, subject to unexpected electrical or mechanical failure.
I used the Gnome Xorg and the lagging was on all pages. Then I did a reset of Firefox. I had done som changes in the about:config, they are maybe the root of this. I have only tested this some hours, but it seems more stable now. The blinking/window update problem is primaryly in Firefox. I hope the reset fixed the problem.
