Worked on the bambulab/BambuStudio repository to address a rendering issue affecting 3D overlay readability on Linux systems using XWayland with Intel graphics. Focused on stabilizing the user interface by adjusting font texture dimensions to comply with OpenGL texture size constraints, this solution reduced visual artifacts and improved the clarity of 3D overlays. The fix was backported from OrcaSlicer and validated through Flatpak and Flathub testing pipelines to ensure cross-platform consistency. Leveraging C++ development skills alongside OpenGL and UI/UX design expertise, the work enhanced the reliability of 3D rendering and maintained regression safety across Linux environments.
