Questions[google-chrome](ubuntu)

• Kubuntu 20.04, 64 bit
• GPU: Geforce GT610
• nvidia-driver-390
• Chrome Version 85.0.4183.83
• Intel i5-4430, core 4, 4 thread , 3GHz
• RAM: 16GB

Each time I go into suspend mode and then resume, Chrome browser displays the current tab as full of sand of colors, something like dithering in image processing.

Other tabs display glitches too.

The current solution is to close and reopen the browser.

I tested nvidia-driver-418 but got a black screen problem and reinstalled nvidia-driver-390.

The problem is more evident in Chrome, but it sometimes appears in vscode in small areas. There, hovering the mouse over the affected place or resizing the window fixes the problem. In Kubuntu the avatar of the user in the application launcher also shows dithered.

I tested in the same machine with fedora 32 workstation(gnome), nvidia driver, and had the same problems with Chrome browser.

Could it be a GPU problem?

I've upgraded from 4.4.0 to 4.4.8 and then 4.5.2 on Ubuntu 16.04 LTS 64-bit, and it's still happening.

At 4.5.2 it's even more frequent, and mainly in Chrome (haven't tried firefox or opera just yet). Every time I open a new web page. Any way to fix that, or is it a bug?

How To Enable WebGL In Chrome On Ubuntu ?

In Google Chrome, when I go to a login page, a window pops up asking to "Enter password for keyring 'default' to unlock". In most cases, whether I click Cancel or enter my password, the login form gets auto filled anyway.

How do I get rid of the popup? I want it to auto login each time, not ask for my system password. The dialog box never appears for any other apps.

I used Google Chrome in Windows, and am now using Chromium in Ubuntu. Is there any difference to the two programs? What are the advantages and disadvantages to each program? Which one seems better?
