Thanks for trying it out.
As I’ve already noted here, I’m trying to keep all bug reports consolidated on GitHub. Can we please move this over to the official issue tracker to keep this discussion thread focused?
The display issue you’re running into is a well-known problem with Linux on X11/Wayland. It’s an easy fix with an environment variable, but since it’s an issue with the underlying framework, it’s not something I can simply solve in my own code. I’m tracking all the workarounds / fixes for it in this main ticket, please take a look: Tracking Issue: Linux/Wayland related problems · Issue #306 · CyberTimon/RapidRAW
