IDE adds StyledElements default value to inherited form even though not needed

One coworker can't reproduce. So need more info why that might be,

I have few free plugins installed, like GExpers. Have to uninstall those and try if problem is not in the plugins.

I saw this in Delphi 11.2, whenever I open those files in D12.1 it removes them.

On this project, it is opposite. Or 12.1 patch 1, adds them.

Removed all IDE experts, and tried again and it behaves exactly the same...

 

It seems that I just need to open the inherited form and StyledElements appear right away.

Did you try with a new .dproj file?

I cannot reproduce here with project and steps from the QP issue. Looks like it is caused by something in your system.

Interesting...

I'll get back to it when Coworkers has tested that also.  Some got the same error on production app, but I'll wait for them to check out the trivial test app also.

This appears to be problem with the : Options > User interface > Form Designer > Enable VCL Styles -setting.

Disabling the Mimic* and Enable VCL Styles settings, inheritance works as expected.
