The Bodhi app center is just a website and opens in your default web browser. I'm guessing you need to disable hardware acceleration cuz of old GPU on the browser, or update the browser. Bodhi 5.1 is kinda old.
From terminology command prompt, try:
Code:
sudo apt update
sudo apt upgrade
sudo apt install firefox
Then open the bodhi app center in firefox, see if that works for you:
https://appcenter.bodhilinux.com
Or to open chromium without hardware acceleration, try:
Code:
chromium --disable-gpu
Then while it's open go to settings and disable it for next time. (Scroll down to the bottom and select the “Advanced” option. Scroll to the “System” section and toggle “Use hardware acceleration when available” and turn off)
