February 2026 monthly summary for longbridge/gpui-component: Implemented a targeted Linux window resize cursor fix to improve UX. The resize cursor was erroneously shown when the window was maximized or snapped to a screen edge; root cause was unconditional SHADOW_SIZE insets applied every frame. The fix guards the inset updates by checking the tiling state each frame and zeroing the inset when fully tiled, ensuring the resize hitbox is only active in appropriate contexts. The change was implemented in commit 88f2d9049d2ed334f9dd7d8e7dfbbcda94ed8609 and validated with Linux client-side decoration tests and cargo run story tests. Result: resize cursor now behaves correctly across Linux states, reducing accidental resizes and improving consistency. Impact: Improved Linux UX consistency for window management with minimal risk, clearer separation between tiled and non-tiled states, and preserved expected behavior for normal windows. Technologies/skills demonstrated: Rust, UI hitbox logic, state-driven UI updates, Linux client-side decorations, testing with cargo, code review discipline, and contribution hygiene.
