Ubuntu Linux 24.04: Presentation is not shown on selected screen

Hi,

We are trying Presenter as an alternative on our Ubuntu Linux 24.04 LTS system. We have an nVidia Geforce GTX 1050 Ti graphics card with three outputs (2 HDMI and 1 DVI), and we are using them all. Our beamer uses an old resolution with 1024x768: Both possible screens for projectiong are recognized.

I started presenter from the console with the parameter '--no-sandbox', otherwise it does not run. When it starts, I see in the console that GPU acceleration is not available.

The problem: If I configure to use the screen for the beamer (Anzeige 1), nothing shows up. It only works, when I use the second screen (Anzeige 2). Then, I see also a short flickering when this screen is initialised. We use the nVidia proprietary drivers. Any ideas what could resolve this?
