QR-Codes are not recognized on digital displays

[ArDevKarl]

I'm working on a demo for the HoloLens 2 that requires the physical input of generated links. To workaround the laborious process of typing hundrets of letters on the HoloLens, I'm using QR-Codes.

Everything works as intended, when I print the QR-Codes on paper. The goal is to scan QR-Codes from my phone or computer display. Now the HoloLens seems to have big problems to recognize QR codes on digital displays. On my PC monitor I need to stare at it for a long time, to get it to scan and on my phone it never works.

I suspect that the reflection of the infrared light interfering with camera image might be the problem here. Does anyone have an idea how to tackle this?

Using the latest OS:

PS: The same happens in the main menu of the HoloLens, not just my application
