Scaler 3.2.0 GUI black screen in Fender Studio 8 Pro (Win11 Build 26200, RTX 4070 Ti SUPER, 150% DPI, multi-monitor)

Hello Scaler Music Support,

I’m experiencing a GUI rendering issue with Scaler 3.2.0 in my DAW. The plugin loads, but the UI is mostly black (only a small top/header/logo area is visible). This makes Scaler unusable.

Product:

  • Scaler 3 version: 3.2.0
  • DAW: Fender Studio 8 Pro (Windows)

Issue:

  • What happens: Scaler 3 window opens but the main UI does not render (black screen).
  • Expected: Full Scaler 3 interface should display normally.
  • Frequency: Always (reproducible)

Reproduction steps:

  1. Launch Fender Studio 8 Pro.
  2. Insert Scaler 3 (plugin) on a track and open the UI.
  3. Result: UI stays black / not rendered (only header/logo area visible).

System information (from DxDiag):

  • OS: Windows 11 Pro 64-bit (10.0, Build 26200)
  • DirectX: DirectX 12
  • CPU: AMD Ryzen 9 3900X 12-Core (24 CPUs) ~3.8GHz
  • RAM: 32 GB
  • GPU: NVIDIA GeForce RTX 4070 Ti SUPER
  • NVIDIA Driver Version: 32.0.15.9174 (WHQL), Driver Date: 2025-12-30
  • Hardware GPU Scheduling (HAGS): Enabled (True)
  • Windows scaling / DPI: 150% (144 DPI)
  • Multi-monitor setup (Extended):
    • 2560x1440 @144Hz (TFG32Q16G, HDR supported)
    • 3840x2160 @240Hz (AW3225QF)
    • 2560x1440 @144Hz (LG HDR QHD)

Troubleshooting attempted:

  • Updated GPU driver to latest installed (32.0.15.9174).
  • Tested with current Windows scaling (150%).
  • (Add any you tried: reinstall Scaler, DPI override, different host/standalone, single monitor, etc.)
