Works fine on my end. It's possible it's been fixed in recent versions

I've tried a few things but I didn't really get anywhere. Added --dlsym as a launch parameter, and that exhibited the same issue.

Running with MANGOHUD_LOG_LEVEL=DEBUG as well didn't output anything that could be interesting, from what I could tell.

@flightlessmango I ran the game with its native Linux build - haven't tried Proton and I'm not interested in trying it out yet. Based on your screenshot, you also ran native?

[flightlessmango]

Yes I also used the native Linux build

Run steam from the terminal then run your game, when you get the error exit steam, the terminal might give us an exact error, or at least where the problem is happening.

Try disabling the steam overlay for europa and then launching the game, that might solve the issue for you.

You can also try using another launcher such as heroic or lutris, and adding the game to those launchers, you'll have the option of using different wine versions (as well as proton-ge). Experiment with different versions and show us the results.

I've told you about a similar error before, If you can remember. It was happening on the Stellaris launcher too on Fedora 39 KDE. Now that I am on a fresh install of Fedora 40 KDE, it is still happening.

[RaduAvramescu]

@fallenexistence0 I've already tried disabling the Steam overlay for EU4, which unfortunately didn't work.

As for running Steam from the terminal, there is no terminal output when that error in the game's launcher appears. The launcher can still be interacted with as well (I can press "Play" again, and the same error pops up, for example, but nothing new in the terminal).

Running the game with both Sway and Hyprland produces the same issue (this is from the same KDE install though, so it's not the Sway spin of Fedora nor a minimal install with Hyprland).

I'll wipe my install and try out Fedora 40 Workstation. I'll come back with an update regarding whether or not MangoHud worked for EU4 there.

I'm experiencing the same issue after a fresh install of Fedora Workstation 40 (so, this is Gnome), with fully up to date packages, and just mangohud and Steam installed (both from rpms). The Mangohud version is still v0.7.1, kernel is 6.8.8, and Mesa 24.0.6. Again, this is the native Linux build of EU4 (maybe the Proton version works but I'd rather not resort to that).

It looks like it's not DE specific, but maybe Fedora specific? Or perhaps a newer version fixed the issue, as @flightlessmango noted.
