Issue
I have a problem with Chromium running headless on Raspberry Pi model 4B with Ubuntu 20. For showing the browser, I am using the official Raspberry Pi touchscreen.
The problem is that the locally hosted page doesn't load and it says "Page unresponsive". But, if I press the "Exit page" button and then "Reload" button, it starts to work correctly.
I am using the following command to start Chromium: xinit /usr/bin/sh -c "chromium-browser --kiosk 127.0.0.1:5000". If I run the same command, but use firefox instead of chromium-browser, the page works. I don't want to use Firefox, because it has some other problems in headless mode. This is why I am concluding, that the problem is not with the webpage, but with chromium.
I tried hosting the webpage with both npm run serve and python3 -m http.server 5000 but always got the same problem.
I don't know if that matters, but I get the following error message when running the chromium-browser with the above mentioned command:

Also, if I run some other webpage, for example google.com with this command, I get the same error message, but the webpage shows up without problems.
The webpage is written in Vue.js
Solution
I have fixed the problem by disabling hardware acceleration. I have done that because I have found a similar problem here: https://unix.stackexchange.com/questions/344138/chromium-google-maps-issue
I have done that by adding the --disable-gpu flag to the command.
