Question

I am working on a desktop app which has transparent background.
While it works on my PC, it does not work on my friend’s PC.

He has win11, and in Project Setting I have him turn on:

Window:Transparant
Window:Per Pixel Transparency
Viewport:Transparent Background

Did I miss something?

thanks in advance

Transparency on windows are only a hint to the OS and it needs to be supported by the drivers, the OS compositor, and the display manager as noted in the Window.transparent documentation:

Note: Transparency support is implemented on Linux, macOS and Windows, but availability might vary depending on GPU driver, display manager, and compositor capabilities.

Ahhh, thanks.

I will stop using transparent background then.
