Reading the application's compressed bytes moves to that dispatcher + too whenever they are already mapped. In Blade Ball the worst + `vkQueueSubmit` fell from 140ms to 1ms, its p99 from 4.9ms to 0.05ms, and + the total time spent in submits from 2534ms to 309ms.

A device + without the `timelineSemaphore` feature decodes inline as before, as does a + submit whose `pNext` already sizes arrays by its semaphore counts. +- The mouse pointer jumped when a right-click camera drag ended, and drifted + to the viewport edge during one. The input router inferred pointer capture + from SDL reporting zero absolute coordinates, which holds on X11 but not on + Wayland, where the reported position accumulates the relative deltas and + leaves the window. Motion, button, and wheel events now carry the window's + relative mouse mode. The right-click camera fallback also only captures + inside an experience, so the cursor stays free over the app surface. +- Shutting the window down while an experience was starting or leaving could + free the pointer capture owner underneath the thread using it. Callers off + the SDL thread now hold a reference for the length of their call. +- The TextBox caret did not move when a trailing space was typed in a + single-line field. The final cluster rect SDL_ttf reports stops at the last + inked glyph, so the laid-out width is used there instead. Wrapped layouts + keep the clamp, because their width is the widest line rather than the last. +- Every TextBox keystroke re-ran `TTF_Init`, a fontconfig sort, six + `TTF_OpenFont` calls, and `TTF_Quit` on the render thread. The overlay holds + its opened fonts and reopens them only when the Roblox font or the point + size changes, keeping the current set when a reopen fails. Measured over 100 + rasters, 1.59ms to 0.12ms per keystroke. +- Staged ETC2 copies now carry an explicit host-write barrier.
