Refresh edge-scroll fractions from laid-out scroll positions and repaint when
they differ from the values used by the frame. Preserve the repaint when a
deferred settings refresh has already changed the model.
Cover DPR changes, viewport clamping, detached scroll axes and restoration
with the actual video and cursor widgets in Original and Custom modes.
Verified 87 native Flutter cursor tests on each of macOS and Linux, plus
17 Chrome Web cursor tests.
Use the truncated Linux texture origin while preserving fractional cursor positions and hotspots. Compare painted cursor geometry with the actual video widget in the existing regression tests.
Use Flutter's PNG codec before native rasterization and retain the straight-alpha image cache. Cover both bundled assets through PNG and Windows BGRA registration.
Use the original Flutter image and source hotspot with explicit DPR, retaining the existing view and minimum-size policies. Pin the plugin implementation from rustdesk-org/flutter_custom_cursor#1.
Capture actual Mutter and DXGI cursor metadata, preserve Retina artwork, and invalidate cursor identities when physical pixels or DPI change. Keep straight-alpha colors during native cursor resizing and correct the Windows XOR outline offset.
Verified all six Mac/Linux/Windows directions with real pointer movement, arrow/I-beam/crosshair transitions, adaptive zoom off/on/off, Original view, and live DPI changes. Requested debug builds and focused native/Flutter regressions pass.
Keep Linux/macOS bitmap sizing and painted cursor DPI
conversion consistent, and derive hotspots from the actual scaled bitmap.
Pad tall Linux native cursor buffers with transparency to
preserve the lower half in the hardware cursor plane.
Cover bitmap sizing, hotspots, artwork preservation,
and painting with focused regression tests.
