MDI application desktop scale - icons problem

  • I have a problem with my desktop application. Display scale 125%. MDI example is OK, but my application has invalid icons for minimalizing, fullscreen, and close. 100% scale is without a problem.

    Qt 5.15.0

    @mk33 I'm not sure where the invalid icons are? In the screen shot I can see two windows with valid icons. Do you mean thos in between?

  • On the screen are two windows from applications. The top is Qt MDI example, the bottom is my MDI application. Main window control icons are ok, but icons from MDI window are invalid. Three blurred squares.
