GLXConfigDialog uses arbitrary font, if xfonts are missing

System Information

• Ogre Version: 13.2.4 (Tsathoggua)
• Operating System / Platform: Manjaro Linux
• RenderSystem: ❌

Detailed description

Running a very basic Ogre program which creates an app that inherits from ApplicationContext opens a configuration Window in the Tamil script of Indian. I had to Google heavily to find out what it was.

Clicking the button on the bottom right (partially hidden) does nothing.
Clicking the button to its left crashes the application.

You can find the exact crash reason at the bottom of the log.

It's the exact same issue as in this forum post: link

I assume that the reason it crashes might be because of the strings...

Here is a repository with all files used to build the project: permalink

Update: I managed to run the program. Turns out that I should have selected some rendering subsystem and then pressed the button on the right. I didn't test that sequence before.
It would have been easier if it was in English...

The sample browser has the same issue with the language. So it's most likely system-wide and my code doesn't have much to do with it.

Another update: this post on Unreal forums has the solution to this problem: link

Everything looks fine now.

Still, it would be great if you could add those font packages to the list of required dependencies. Or something.

thanks for investigating! However, given that the config dialog itself is optional (only compiled if Xaw is installed) and requires X11, I would rather drop Xaw from the list of recommended dependencies
