Fix dynamic resizing and minimized queue lifecycle

[zortos293]

Integrates Wheezee's #33 with the merged #34 overhaul. The original five contributor commits are retained in this branch; a replacement PR is necessary because this environment cannot push to the contributor's fork.

Safe dynamic resizing

Build a complete renderer configuration for frame-size, display-size, or hardware/software changes before replacing the active configuration. Keep the old configuration until its final draw fence completes, preserving the frame-storage references and command/upload fences from #34. Failed allocations retain the previous image and retry after 250 ms. Ownership is bounded to one active plus one replacement or retiring configuration; resizing does not call waitIdle in the draw loop. Software color-range metadata is preserved, the NVTEGRA limited-range workaround stays hardware-only, and range changes replace stale shader transforms.

Queue and input behavior

Keep queue minimization, restore controls, queue position indicators, screen-awake behavior, and configurable reminders from #33. Use #34's allocation ownership for cancellation and stream handoff. Cancel stops the allocation before the dialog transition, dismissal detaches UI pointers, and progress updates remain on the UI thread. Prevent overlapping launches and reject completion after an account change. Keep the queue chip visible before a position is available and notify once per launch.

Retain negotiated-desktop touch coordinates and the four direct editing keys. Touch-only controls are separate from the existing eight controller shortcuts.

Verification

• Host checks pass normally and under GCC ASan/UBSan, including the added actual-renderer color-range regression.
• Actual-renderer tests inject failures at 26 software and 11 hardware allocation sites during initialization and replacement. They also cover retry, repeated resizing, stalled completion, backend/screen changes, and retained storage with stubbed GPU operations.
• An extracted-production queue lifecycle check passes under ASan/UBSan, covering cancellation, late allocation, dismissal, restore, and stale cleanup.
• The supported Switch build passes in the pinned devkitPro container and produces SwitchNOW.nro.

Live NVIDIA gameplay, visual UI behavior, SPS changes, dock/undock, and latency still require Switch hardware acceptance. Host GPU stubs and an NRO build do not prove those behaviors.

Summary by CodeRabbit

• New Features

  • Added queue status and position to the top bar, with controls to minimize and restore queued sessions.
  • Added a configurable “Queue notify at” setting with thresholds of 5, 10, 20, or 50.
  • Added touch controls for Backspace, Delete, and left/right arrow keys.

• Bug Fixes

  • Improved touch and pointer accuracy by using the negotiated stream dimensions.
  • Improved video handling when stream size, format, or hardware/software rendering changes.
  • Added clearer notifications as minimized queued sessions approach readiness.

📝 Walkthrough

Walkthrough

The change adds GPU renderer reconfiguration, minimized cloud-launch queues, queue notification settings, keyboard touch controls, negotiated input dimensions, and host tests for these paths.

Changes

GPU renderer reconfiguration

Layer / File(s)	Summary
Configuration lifecycle app/src/stream/deko3d/DKVideoRenderer.*, app/src/stream/deko3d/GpuConfigurationQueue.hpp	The renderer now manages active and retiring configurations, validates frames, defers frame submission, retries failed replacements, and releases configurations after completion.
Renderer validation and host execution tests/deko_renderer_*, tests/run_deko_renderer_reconfiguration_test.py, .github/workflows/host-tests.yml, scripts/test-streaming-host.sh, docs/switch-streaming-audit.md	Tests cover allocation failures, retries, retirement, backend changes, bounded retention, and mapping exceptions. Host execution now installs pkg-config and runs the renderer tests.

Queued cloud launches

Layer / File(s)	Summary
Queue session lifecycle and restoration app/src/ui_helpers.*	Launch state now supports minimized dialogs, restoration, cancellation, stale-session checks, queue position updates, and completion cleanup.
Queue notification setting app/src/stream_settings.*, app/src/settings_tab.*, tests/queue_notify_settings_test.cpp, scripts/test-host.sh	The queue notification threshold supports values 5, 10, 20, and 50, with persistence, sanitization, settings UI cycling, and host coverage.
Queue status display app/src/top_bar_frame.*, docs/switch-streaming-audit.md	The top bar displays queue status and restores minimized queue dialogs through the queue chip or controller chord.

Input controls and negotiated dimensions

Layer / File(s)	Summary
Negotiated input coordinates app/src/webrtc_session.hpp, app/src/StreamView.cpp, app/src/stream_view_input.cpp	Input coordinate calculations now use negotiated desktop dimensions.
Keyboard touch controls app/src/keyboard_input_policy.hpp, app/src/stream_view_input.cpp, tests/keyboard_touch_controls_test.cpp, scripts/test-streaming-host.sh	The touch keyboard adds Backspace, Delete, Left, and Right controls with mapped key events, updated layout, and geometry and event tests.

Merge Risk: 🔵 Low · up to 5214a

Full-range software video can render with incorrect brightness and contrast. The defect is localized and should be corrected, but does not threaten renderer stability or data.
