TOPIC:

Did a lot of experimenting on Linux Mint 22.3 (GTK2) with windows that have a gradient background (plGradient) and Checkbox and/or DBCheckbox components and it is still very unpredictable.
On my Linux test project I sent you earlier everything works as expected but on one of my projects everything works fine on my Windows 11 machine but I keep having the checkboxes hidden by the background gradient even after moving the gradient to the back.
See the attached screenshot.
I hope you can give me any suggestions, for this is really getting me crazy.
