Bug Description
In most application there is "not responding" window displayed. Firefox, Google Chrome, Google Remote Desktopm (=Chrome). In Google Remote Desktop the sound is transfered in a "okish" delay. The display of the remote machine is delayed by about 2-5 seconds.
The laptop is connected by wifi, the remote machine is connected by lan cable.
The problem also occur if the laptop is used in the same network about 2-3 meters away.
There seems to be a driver issue. If graphic, "chipset", ram or harddisk: I dont know. The machine is very old but is quad core with 4 gb of ram. There SHOULD be a better performance.
I used a dual core about 3-4 years ago and the performance was similar to this laptop now.

Thanks for the bug report. I can see two main problems here:
1. The amdgpu kernel graphics driver is emitting warnings that look like crashes.
2. The rtw_8821ce kernel wifi driver is flooding the system log (this is probably the performance issue).
So I can only suggest trying an older Ubuntu release like 22.04.0 with an older kernel:
https:/ /old-releases. ubuntu. com/releases/ jammy/ubuntu- 22.04-desktop- amd64.iso
or trying newer kernels from:
https:/ /kernel. ubuntu. com/mainline/ ?C=M;O= D
or disable wifi and use wired networking;
or replace the wifi card in the laptop with an Intel one.
