Closing a busy split or confirming a tab close could freeze GTK while unrealizing the GLArea. Both reported GDB traces show the main thread waiting for the CPU frame-state mutex while the renderer keeps rebuilding dense text. GTK unrealizes the display before stopping the workers, so continuous output can keep the competing renderer active indefinitely. Use parking_lot fair mutexes for CPU frame state and GPU draw state. A waiting lifecycle or draw callback receives ownership instead of losing it to the next frame update. Keep the existing lock order and resource cleanup; no output, scrollback, or frame-rate limits are introduced. The fair-lock handoff adds scheduling overhead when the locks are contended. Correct the threading documentation: the CPU state is also accessed by apprt callbacks, and the Rust-only mutex is therefore contended. Test plan: - Add a mock GPU regression continuously rebuilding 200x150 dense cells while another thread unrealizes and realizes the display. It failed its three-second deadline with the old locks and passes with fair locks. - All 235 renderer/core tests pass, including Mesa EGL rendering tests. - Clippy for renderer/core/GTK, all targets, passes with -D warnings. - Nightly formatting check and release binary build pass. - GTK/Wayland replay with font size 9 and 1 GiB scrollback runs base64 floods in two splits, confirms split and tab closes, then successfully executes and renders a command in the surviving terminal.
