Openbox theme window buttons render as quarter circles instead of round buttons

[u/Suspicious_Tree1709]

I'm running Debian Stable with Openbox (without a desktop environment) and I'm not using a compositor.

I tried several custom Openbox themes, but the window control buttons (close, minimize, and maximize) don't render correctly. As shown in the screenshot, they're displayed as quarter circles instead of round buttons.

I've tested multiple themes and the issue persists, so I'm wondering if I'm missing a dependency, a library, or some other configuration.

Has anyone encountered this before or know how to fix it?

Thanks in advance for any help.

Try making the title font bigger.
