So I finally bought an I5, 8 GB RAM and a 500 GB SATA PC to get Debian running as smooth as possible. The same has a Intel integrated Video Card.
Everything went excellent, the installation was super fast and easy and the overall experience is good ( I have tested for only two days though and the only problem I did have is that I attempted to install Chrome ( not Chromium ) and the PC entirely rebooted... wtf?!! ), the package was corrupted and I did not want to have a headache with that so I just deleted it and continued using Firefox.
But thats not why I am here. I am here because there is some flickering on the desktop and I dont know how to fix it. I googled a little bit and foudn that many people have/had a similar issue ( some part of the screen goes black for a brief period of time, really short, but enough to make it perceptible ) but those post are from 2016 and before. I am posting this as I have the hope that someone would have found a straight forward way to correct this.
This is the first time I used Debian and other than that, it has been a really pleasant experience, so this is a real bummer.
The flickering occurs most of all when some window lost focus and another one gets it, as well as when I start typing somehtign or I click on an input box.
Im sorry I am not able to paste some of my system details/logs here as I am not at home right now, but being as this is an issue spread across so much different distros and also so old, I really hope someone can give me some advice here.
Thanks in advance!
