FTXUI Files

Component

• Bugfix: Fix high CPU usage (app and terminal emulator, e.g. tmux) caused by a cursor position request/reply feedback loop redrawing the screen at ~60fps in the non-alternate-screen modes. See [#1302].
• Animation frames are now produced only when requested via animation::RequestAnimationFrame() (e.g. by animation::Animator), as in FTXUI 6. Receiving an event no longer implicitly triggers an animation frame.
• Bugfix: App::PostEvent is now thread safe again, as documented. Since the 7.0.0 event loop rework it pushed into an unsynchronized buffer, racing with the main loop when called from another thread.
• Bugfix: Fix unbounded memory growth in the event buffer. A receiver used during terminal setup was kept for the whole App lifetime, retaining every subsequent event (including every mouse move).

Dom

• Performance: text computes its requirement once and renders only the visible lines. This makes scrolling a large text inside a frame significantly faster. Thanks @patlefort. See [#1309].
• Performance: text selection now only visits and stores the selected line range, instead of scanning and allocating one entry per line of the whole text on every frame.
