Regular minimal stutters while dual monitors are turned on

cn flag

Summarize

I have installed Kubuntu next to Windows 10. Displaying stutters while botch of my monitors are turned on.

Details

However this problem appear also on other distributions. (Pop OS 20.04 LTS (NVIDIA), KDE Neon, Manjaro). I thought that only my mouse stutters because when I am moving it, it stops regular and then move again. Furthermore while I am typing or I am watching something on youtube stutters also occurs.

When I turn off my second monitor, everything works fine. I have no stutters, everything is smoothly.

What I have tried

Full update and upgrade of system.

Installed newest Nvidia drivers from: https://www.nvidia.pl/Download/driverResults.aspx/175963/pl

Set the same resolution and refreshing on both screens.

Turned off HiDPI Daeomon

Removed indicator-multiload sudo apt-get remove --auto-remove indicator-multiload

Only Ubuntu and *official* flavors of Ubuntu (https://ubuntu.com/download/flavours) are on-topic here, refer to https://askubuntu.com/help/on-topic where you'll find other SE sites where you question will be welcome if you don't want to use the Pop forum. (*One advantage of Ubuntu is it's many support options, you opted for Pop OS so take advantage of its support options, or SE Unix & Linux* found in the on-topic link)

@guiverc Should I change from Pop OS to Kubuntu and result will be the same? :P I said I have the same problem on Kubuntu which is one of the flavors. Firstly I have installed kubuntu. I had this problem then I switched to PopOS which is based on Ubuntu and result is the same.

Kubuntu is on-topic & using what Ubuntu have deemed *stable* software. Pop OS doesn't use a Ubuntu kernel and is based on a *testing* grade kernel (eg. Ubuntu on 20.04 will get the kernel Pop OS use on release of 20.04.3, and *development* software is off-topic here until release). Pop also compile the kernel themselves, thus your kernel modules (drivers) maybe different. Pop OS is thus off-topic here, and your software stack is different. (Neon likewise use a different stack & is off-topic, but it's using the Ubuntu kernel with other software changed.. See first comment as to what's on-topic)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
