Qt AppImage fails to open on CachyOS + AMD GPU with vulkan enabled

[luna15161718]

Is there an existing issue for this?

• This is a bug in RetroArch frontend
• I have searched the existing issues

Description

Qt AppImage does not start with video_driver = "vulkan"
This bug can be resolved on my system by removing libxcb-present and libxcb-randr
Replacing them with the libraries from my system makes it run on my system, as well as Ubuntu 24.04 through Distrobox but not Ubuntu 22.04
A similar issue seems to have been reported in #13714 but that seems to be an issue with a different library
This issue does not arise using the non-Qt AppImage or on my laptop running the same distro but with an Nvidia GPU

Expected behavior

Retroarch opens

Steps to reproduce the bug

Use a PC with CachyOS (might happen on other arch-based distros) installed and an AMD GPU
Set video_driver = "vulkan"

Probably the same as this issue: #13714

If so, let's close this one out in favor of that older one.

[luna15161718]

It isn't as that was an issue with different libraries

[hizzlekizzle]

Oh, I see that you mentioned it. My bad. Ah, and the non-Qt one works fine for you.

Well, I'm not sure there's much we can do about this without breaking it on other distros. That is, I think it's a conflict between system libs and the bundled libs. At least, that's what we've run into with related issues.

Looks like it errors out on Vulkan context initialization?
