    Hello,

    there are occasional graphics glitches in my Qt app on Windows with Qt version v5.15.x. The problem does not occur under Linux. Also not under Windows from Qt version 6.x.

    Does anyone happen to know about this problem?

      There are many possible causes for graphical glitches. Try setting the environment variable, QSG_RHI=1. Does that fix the issue?

      If not, please post a minimal compilable example project.

        Hello,

        thanks for your reply and sorry for the delayed answer.

        At the moment, all graphic glitches are gone but I don't know why,

        When I set OSG_RHI=1, all things using QtGraphicalEffects (e.g. DropShadow, Gradient, ..) doesn't work any more. So this seems not to be an option for me.

        regards,
        Tobias
