Freak xrandr scaling mode bug (tiktok aspect ratio)

I'm trying to play some old games in 4:3 in my laptop, but when i run this command for preserve 4:3 aspect ratio...
xrandr --output eDP-1 --set "scaling mode" "Full aspect"

My games and my display(1024x768) looks like a tiktok video non like 4:3 aspect ratio

My original display is 1366x768, I'm using Arch Linux , amdgpu open source.

P.d: I'm trying to fix this puzzle and this bug is related with the monitor, when I use my laptop monitor with Center scaling mode it crash, and when use full scaling mode in my external monitor it works properly.
Is very strange

Re: Freak xrandr scaling mode bug (tiktok aspect ratio)

xrandr --props
xrandr --verbose

looks like a tiktok video

There're weirdly dancing influencers on your monitor?

You mean its getting letterboxed? Or pivoted?
Linking a photo might help to understand what you think is a tiktok video (other than the end of of human civilization)
Also document the states using "xrandr -q"

I assume just running the output on XGA (xrandr --output eDP-1 --mode 1024x768) gets you a stretched display?
Can you control the output via https://wiki.archlinux.org/title/Xrandr … -transform

I'm using Arch Linux , amdgpu open source.

And please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General - xf86-video-amdgpu ./. modesetting might have a huge impact here.

Re: Freak xrandr scaling mode bug (tiktok aspect ratio)

I assume just running the output on XGA (xrandr --output eDP-1 --mode 1024x768) gets you a stretched display?

Only when i use
xrandr --output eDP-1 --set "scaling mode" "None"
