DisplayXR v2.9.0

[2.9.0] - 2026-07-28

Fixed

• App-authored 3D zones were corrupted in the editor's docked weave-to-texture Play Mode (#233, #234). An app that authors its own 3D zone (a 3D band with a 2D/Local2D band beside it — the desktop-avatar pattern) rendered with the content truncated and a matching black band, a visibly magnified/broken weave, and its 2D band missing. Two bugs, one stale assumption — "the 3D zone is the full pane", true only while the provider was forcing it to be:
  • dxr_prov_converge_gameview_zone() paired the app's zone offset with the Game view pane's extent, producing a zone that overran the pane (e.g. (0,284) 1728x576 → (0,284) 1728x860 in an 860-tall pane) and a compositor viewport that overflowed its tile. Converge now repositions an app zone (pane origin + app offset, extent preserved, clamped) and never redefines its extent; the app-authored rect is recorded separately so converge is idempotent.
  • dxr_prov_get_woven_canvas() returned the zone as the GameView mirror's source rect. Since the mirror stretches that to fill the Game view, a sub-window zone was magnified — destroying the lenticular interlace and never sampling the 2D bands. It now returns the pane, which is what the runtime actually composites into the shared texture.
• State pushed once before the session started was silently lost on every session restart (#233, #234, #235). The editor's docked↔undocked switch restarts the display subsystem mid-play, and session stop clears the provider's session state; because each C#→native push is change-detected or once-only, nothing re-pushed. Fixed for all six affected paths — the 3D zone (both render paths, not just the docked one), the transparent-background opt-in (sessions came back opaque), extra/multi-zone rects, the Local2D bridge and rect, and the DisplayXRWindowSpaceUI bridge. Bridges are now re-acquired by detecting the native pointer change rather than assuming a non-null wrapper is still live — a wrapper around a destroyed resource accepted copies silently, so the failure had no error signature.

Changed

• dxr_prov_get_woven_canvas() now reports the Game view pane rect rather than the active 3D-zone rect. Identical for apps that author no zone (the provider's forced zone equals the pane); different only where an app authors a sub-window zone, which is the case this fixes.
• dxr_prov_set_transparent_background(), dxr_prov_set_zone_count() and dxr_prov_set_zone() now persist their request across session restarts instead of applying only to the session that was live when they were called.
