Proposal to fix QMenu's display Affinity.

[brazosbuckaroo]

Howdy all!

While looking at reproducing the following Issues:

#12407
#11678

I found another little unexpected feature. QMenus do not have the correct display affinity:

2026-09-02.19-36-23.mp4

Currently my thought process is to create a class that inherits QMenu. It will then override the showEvent function to get the window handle and properly set the Affinity. So, cmake will include correct file based on platform but the class name and file name will be the same, ideally. This, of course, is mostly for Windows 11, but I did see that there was a TODO to implement that for other platforms.

Really, I am curious to see what ya'lls thoughts are about solving in this manner? I am new to working on other projects and wanted to get ideas. I have a branch to look if ya'll have time. It's in the early stages; however, it proves that this at least fixes the issue. The only downside is that the context menus quickly flash, but I cannot see an easy way around defect.

Repro:

1. Launch OBS Studio
2. Open Settings
3. Enable Hide OBS from Capture
4. Press Ok
5. Right click on the preview
6. Notice the Context Menu shows up

Expected Behavior:
OBS Studio should not capture any UI

Best,
Daniel
