I don't know what happened. I loaded up the game and was messing with settings, when this happened. I accidentally clicked something I wasn't even looking at and instantly my screen turned into one big square of color. This happened in the vanilla game, I had just gotten done removing old mods and did a fresh install. Screen will change colors to something like an average of the color where my mouse is hovering. I recognize the color of the menu sometimes as I move the mouse. Will also go black brown and white.
UPDATE: after some more digging, using "-screen-height 1080 -screen-width 1920" in launch options fixed the problem, however I will leave this here for posterity.
Hello William L.
This issue seems to be some mod that broke after we updated valheim rescently.
The fix you mention works 100% for all people who tried it =)
(Use whatever screen resolution your monitor is set to in the -screen launch settings)
How do i fix this on The windows store version??
You can either make a shortcut to valheim.exe file and then add the line like this.
"C:\Program Files (x86)\Steam\steamapps\common\Valheim\valheim.exe" -screen-height 1080 -screen-width 1920
in the shortcut.
Or you can just remove the whole folder in windows registry if you find that easier to do. (ask a friend if you never done it before since it can mess up your entire windows installation if you remove the wrong folder)
