Could you give a bit more information about the hardware and software setup?
- which GPU do your desktop and laptop have? (from what I could find online, the A285 has an iGPU from 2019. I really hope this is wrong)
- wayland or X11?
- hoi4 native or via proton?
I believe I had similar issues on my Nvidia GPU, but resizing the window was a complete fix in my case.
You could try adding the
__GL_THREADED_OPTIMIZATION=1
environment variable to the custom launch options, it improved performance and lessened bugyness for me.You could also try to run the launcher with software rendering^1^ by editing
~/.paradoxlauncher/launcher-v2.2024.1/Paradox Launcher
(you might have to change the version). Try adding--disable-gpu
in the last line, between--no-sandbox
and"$@"
You could also try disabling gamemoderun. It hasn't really improved performance in my experience, but has caused some bugs for me. It also muddies the logs.
