@Will said in Radio button circle becomes colored in when using a scroll area Qt6 on Windows:

Question 1: Is this normal / expected?

Yes since it's the windows 11 style

Question 2: Can this be turned off?

Yes, use the windowsvista style: https://doc.qt.io/qt-6/qstyle.html#setting-a-style

@p3c0 Thanks for the suggestion. Sorry about the delay in replying.

I can achieve a good result by dividing by 1.1 instead of 2. Using 1.1 I get blue box just a little bit smaller than the radio button itself.

For some reason if I make the ration 1.01, the blue box exceeds the size of the radio button.

If I simple divide by 1.0, the application fails to get out of bed.

Thanks
