TransparentBar v0.1.9

Resolves coordinate mismatches and delayed sampling on displays using Windows display scaling (such as 125%, 150%, or 200%).

What comes bundled:

  • TransparentBar.exe - Native Windows host executable (x64)
  • transparentbar_bridge-0.1.9.dll - Native taskbar transparency bridge
  • Inno Setup Installer (TransparentBar-setup.exe) - Standard per-user installation with desktop shortcut option
  • Portable ZIP Archive (TransparentBar-windows-x64.zip) - Standalone package with SHA-256 verification sums

What doesn't come bundled:

  • Fixed 96-DPI assumptions or hardcoded scale factors
    • All metrics scale dynamically using the real DPI of the monitor hosting the taskbar
  • Unnecessary background polling
    • Sampling remains conditioned on maximized window states

New and improved MAJOR features in 0.1.9:

  • Per-Monitor DPI Awareness V2

    • TransparentBar now declares Per-Monitor V2 DPI awareness at startup.
    • Eliminates DPI virtualization where GetWindowRect returned scaled logical coordinates while BitBlt captured physical device pixels.
    • Prevents the sampling band from landing several rows above the actual visible application edge on scaled displays.

  • Dynamic Scaling of Connector Geometry

    • Strip height, seam overlap, sample rows, blur radius, frame overhang, and edge slack are computed dynamically from monitor DPI.
    • At 125% scaling (120 DPI) or 150% scaling (144 DPI), connector elements maintain precise physical pixel alignment without distortion.

  • Scaled Maximized Docking Tolerances

    • Windows invisible resize frames grow proportionally with DPI scaling.
    • Docked-window detection now adapts to scaled window overhang, preventing false rejections of maximized windows on high-DPI displays.

Note

SetProcessDpiAwarenessContext and GetDpiForWindow are resolved at runtime via GetProcAddress, preserving full backward compatibility with older Windows 10 releases while enabling Per-Monitor V2 on modern builds.

New and improved minor features in 0.1.9 include:

  • Runtime Verification: Added automated tests verifying the DPI scaling table, docking decisions from 96 to 288 DPI, and Per-Monitor V2 awareness context.
  • Fallback Safety: Falls back gracefully to system DPI awareness if Per-Monitor V2 is unsupported by the host environment.

  • Metrics Calculation: scale = (base * dpi + 48) / 96 provides integer rounding across all standard scaling tiers.
  • Test Suite: 15 host tests and 7 bridge tests passing.
