[Linux] Window control buttons displaying Windows style instead of native Linux theme

[everton-matos]

Environment

• OS: Ubuntu 24.04.3 LTS
• SourceGit Version: 2026.01

Description

When running SourceGit on Ubuntu Linux, the window control buttons (minimize, maximize, and close) are rendering in Windows style instead of using the native Linux/Ubuntu theme.

Expected Behavior

The window control buttons should match the native Ubuntu/Linux desktop environment theme and styling.

Actual Behavior

The application is displaying Windows-style window controls (see screenshot below), which appears inconsistent with the rest of the Linux desktop environment.

As shown in the image, the minimize, maximize, and close buttons (highlighted with the red arrow) are using the Windows visual style instead of adapting to the native Ubuntu theme.
