Worked on the YaLTeR/niri repository to address a rendering issue affecting OpenGL ES 2.0 GPUs, focusing on restoring accurate blur effects by correcting framebuffer binding logic. Applied expertise in Rust and graphics programming to identify and resolve the root cause, ensuring that visual fidelity and device compatibility were maintained across the ES2 rendering path. The solution involved updating regression tests and release notes to document the fix and validate its effectiveness on relevant hardware. This targeted bug fix improved the stability and consistency of the rendering pipeline, demonstrating a methodical approach to diagnosing and resolving low-level graphics issues using OpenGL.
