How to troubleshoot game fullscreen issue

Hello, I'm relatively new to linux and was wondering what steps I need to take to troubleshoot an issue I started having with one of my games? This is in part asking for help but also a general 'how do I approach things like this in the future so I don't waste people's time'

I don't know what all information I need to include about my system. To start I'm using Arch btw, KDE Plasma, Wayland, on a Framework 16 with the AMD Radeon 780M built in gpu.

My problem is at some point between when I last played the remastered Life is Strange about a month ago and now the fullscreen option broke. As far as I can tell the game appears to be running but when I'm in game it visually looks frozen. I can still do things like move my cursor around, navigate menus, etc. I get sound fine and if I alt-tab out then in the screen will be updated to the new menu but frozen from there. Windowed and borderless windowed work as expected.

I noticed a general vibe of 'try switching to X11' when it comes to things like this so I've done that and it does appear to work here. So while it is a good workaround I would still prefer to know how to either fix the issue when using Wayland or where I need to go and what info I need to provide to make a bug report.

Thank you for any help!
