[FIXED] Error on screen rendering on startup (Rainbow Style)


I’ve just installed Manjaro, and each time I start my computer I have this “rainbow effect” : https://ibb.co/7WhCxvH

I am the first one to defend the subjective point of view of beauty (really) but here… Well hum…

Joke aside, the problem seems to solve when I open the display menu, apply a random screen definition and click on “Restore the previous configuration” so I think there is something messing up on startup…

I’m using 1920x1080 resolution on a Lenovo laptop.

Before manjaro I was using a classic Arch Installation switching between xfce and i3 and I never met this issue so maybe you’ll see what I’m missing here.

Thanks in advance

PS: Pardon my english, it’s not my native language


Step 1: Uninstall Manjaro
Step 2: Install Arch Linux vanilla style

I should never have left in the first time…
