@SGaist My experience is different. The computer reported having DirectX 12 but it didn't work. Anyway, I am no longer worried about this particular computer.
Thanks

@Chris-B Hi, and welcome to the Qt forum! Please post the exact text of the warning and please show us the code that triggers the warning.

Hi,

Looks like a regression, you should check the bug report system to see if it's something known. If not, please consider opening a new report providing a minimal compilable example showing that behavior.

@SGaist
Thank you very much! The wrong installer was the problem.

QTBUG-52230 should rather be followed.

Looks like this bug has been found and fixed since 5.6 beta was released. I will double-check but then likely this should be marked as answered and fix will be in 5.6 release version :)
