The following is my ubuntu information:-

$neofetch

Kernel: 5.13.0-30-generic
Uptime: 2 mins
Packages: 2774 (dpkg), 1 (flatpak)
Shell: bash 5.0.17
Resolution: 1920x1080

WM: Mutter
WM Theme: Adwaita

When I scroll pdf files or webpages, my ubuntu keeps lagging. I don't want to reinstall it, hence, why I am asking for help.

I also checked my RAM usage and it seems to be normal. However, CPU usage seems to get high when my computer starts to lag. Below is an image of my CPU usage while I am scrolling a pdf document:-

This all started when I closed my computer by pressing and holding on the power button once.

Please do tell me what other information I should provide so as to make this issue clearer.

I just solved my problem just by pressing and holding down on the power button. So the issue is solved.

    No, it's not. Please stop doing that and either shutdown properly or reboot. Brute forcing the shutdown will at some point produce errors that may not be easy to correct. – ChanganAuto Mar 03 '22 at 10:53
  • Instead of shutting down by holding down the power button you can use REISUB, i.e. hold down the Alt+SysRq (usually PrtSc on laptops) buttons and at the same time press the following letters one by one R, E, I, S, U, B. For what this does see this answer. – BeastOfCaerbannog Apr 04 '22 at 09:07
