--- Comment #3 from Maik Qualmann <metzping...@gmail.com> --- The problem depends on the graphics card. I can reproduce the problem on a computer with an embedded Intel graphics card. The video runs well on a laptop with an AMD GPU. I want to test whether we can change something using environment variables. Otherwise, I would report the problem to Qt.
