Worked on stabilizing Wayland rendering in the zed-industries/zed repository by updating the WgpuRenderer to prefer VK_PRESENT_MODE_MAILBOX_KHR, with an automatic fallback to FIFO to prevent event loop stalls. This approach reduced UI freezes and improved rendering smoothness across various Linux driver configurations. The solution was implemented in Rust, leveraging GPU and system programming skills, and included both automated tests and manual validation on NVIDIA proprietary and Mesa RADV drivers. Release notes were updated to document the changes, and the work contributed to broader Linux Wayland stability, ensuring a more responsive user experience without regressions on X11 platforms.
