I changed the graphics card - freezes picture

I had 3 "NVIDIA NVS 300 Dual-VGA" with 6 monitors. I switched to 2 "NVIDIA Quadro NVS 450" cards for 8 monitors.

The picture is not smooth, i.e. the cursor is not smooth. Moving windows between monitors works smoothly. Sometimes it breaks off the sound of the click.

I have installed packages:

xorg-server
xorg-xinit
xf86-input-evdev
xf86-input-mouse
xf86-input-keyboard
mesa
xf86-video-nouveau
xf86-video-vesa
xf86-video-fbdev

lspci | grep -e VGA -e 3D  
05:00.0 3D controller: NVIDIA Corporation G98 [Quadro NVS 450] (rev a1)
06:00.0 VGA compatible controller: NVIDIA Corporation G98 [Quadro NVS 450] (rev a1)
09:00.0 3D controller: NVIDIA Corporation G98 [Quadro NVS 450] (rev a1)
0a:00.0 VGA compatible controller: NVIDIA Corporation G98 [Quadro NVS 450] (rev a1)

plasmashell --version
plasmashell 5.19.5
kf5-config --version
Qt: 5.15.1
Szkielety KDE: 5.74.0
kf5-config: 1.0

I have XRender turned on. Changing the mode (slow | fast) doesn't help.

I carried out the command

kquitapp5 plasmashell && kstart5 plasmashell

I notice on the notification screen:

Re: I changed the graphics card - freezes picture

Have you tried Nvidia proprietary drivers instead of nouveau ? If I remember correctly, can't have both installed same time, or it is not recommended.
Of course PSU must have some capacity for added wattage, all kinds of problems possible with underpowered PSU.
- NVS 300, 18 Watt card
- NVS 450, 35 Watt card
Difference in power usage seems to be pretty small, so I suppose no PSU problem here. 3x18=54, 2x35=70.
Just to mention here (always should be thought when replacing hardware).

Re: I changed the graphics card - freezes picture

Drivers from Nvidia has always been problematic. When I had Manjaro, there was "Dantean scenes". I prefer to stay with the community.

It's hard for me to figure out where to look for the cause. 8 monitors are hard to work with. I wonder if this is the cause of KDE plasma. She was also problematic.

For example, when I get mail on Thunderbird and get a balloon saying I have received the message, the audio cuts out.
