What's the issue you encountered?

I've installed package from AUR. Tried to run it and I get following:

$> imhex

How can the issue be reproduced?

Launch from terminal or launcher

ImHex Version

1.37.4

ImHex Build Type

• [x] Nightly or built from sources

Installation type

AUR package (1.37.4-1)

Additional context?

I'm using manjaro with i3 window manager. I've run ImGui applications in the past without issue so I'm not sure if this is related to ImGui or ImHex

Hi @marinjurjevic , I think I ran into the same problem on Debian 12 today. I've filed https://github.com/WerWolv/ImHex/pull/2390 which fixes it for me.

1. I think you can work around it by setting the IMHEX_SKIP_SPLASH_SCREEN=1 environment variable, could you try if that resolves the issue for you? IMHEX_SKIP_SPLASH_SCREEN=1 imhex should do the trick.
2. If you are comfortable compiling from source, you can try my branch and see if that resolves it.
