…y option After a deploy Safari can load the start page before the updated service worker controls it, so the page has no COOP/COEP headers, no SharedArrayBuffer, and the engine dies with "The object can not be cloned" on a black screen. The start page used to reload only once per tab; it now reloads whenever isolation is missing (at most once every 20 s, so browsers that can't isolate don't loop), and the game page does the same instead of starting without threads. Graphics quality (start page segmented control, and "Graphics" in the in-game ••• menu, applied on next launch): - Standard: 540p, quarter-size textures (previous behaviour, default) - HD: 720p, half-size textures - Max: full screen resolution, full-size textures The chosen quality is included in Copy diagnostics.

With the engine now asking for the page-sized mode (1168x540 on an iPhone 11), CShaderDeviceMgrDx8::ValidateMode compared it with the GL layer's fixed 640x480 "display mode" and refused it. SetMode failed, CreateGameWindow returned false, ModInit failed and the engine exited right after "[Render360 video] mode 1168x540" with RUN_OK and nothing on screen. A browser canvas can be any size, so skip the windowed size check on web.

Black screen
Diagnostics showed
crossOriginIsolated=falseandSharedArrayBuffer=undefined, followed by "The object can not be cloned" while workers were starting. GitHub Pages can't send COOP/COEP headers, so the service worker adds them. After a deploy, Safari can load the start page before the updated worker controls it. The start page's "reload once" guard was per-tab, so it never retried.Graphics quality
