As stated I have screen flickerings (see lightning like flickering on photo attached for portrait screen, for horizontal screen I also have screen flickering on the upper part but hard to catch in a photo) on freshly installed Ubuntu 20.04 LTS. I have tried this: https://askubuntu.com/questions/1231441/ubuntu-screen-flickering and this: https://learnubuntumate.weebly.com/screen-tearing-on-intel-graphics.html without success. I have also seen some other people mentioning screen flickering on ubuntu 20.04 here: https://www.reddit.com/r/Ubuntu/comments/fvk536/anyone_else_noticing_window_flickering_on_ubuntu/ without solution. I also know that it is very unlikely hardware problem because my screens were displaying well on archlinux. I think my graphic card info are already included in the report but just in case: Intel Corporation UHD Graphics 630. Might be intel driver problems ? Could you help me on this please ?
