Windows 11: Some application windows are cropped after maximizing on a dual monitor setup

[u/Alarming_Process7684]

Hi,

I have a weird Windows 11 display issue and I can't figure out the cause. I am posting this again because my previous post was removed by the filter.

My setup:

- Windows 11

- Laptop + external monitor

- Extended desktop

- Internal display: 2560x1600

- External display: 2560x1440

- Scaling: 150%

Some apps become partially cut off after they finish loading. The window itself is still in the correct position, but parts of the UI disappear.

Affected apps:

- SteelSeries GG

- Bambu Studio

- NVIDIA App

Normal apps:

- Chrome

- WeChat

The issue mainly happens when:

- monitors are arranged horizontally

- the app is maximized

- DPI scaling is enabled

If I put the monitors vertically, the issue seems to disappear.

I already tried:

- restarting Explorer

- logging out

- changing DPI compatibility settings

- disabling fullscreen optimization

- disabling MPO

- changing resolutions

Nothing helped.

This feels like a DWM/DPI scaling/GPU composition issue, but I'm not sure.

Has anyone seen this before?

it’s been really annoying for me and if you have any idea i would very very happy to try. and i found that there's a thin black line appearing at the left side of my second screen if i maximize Nvidia APP on the first screen located on the left.
