(EMBERGEN/LIQUIGEN/ILLUGEN) Left-click detection causes unintended node movement and parameter value changes when application is maximized

Software Support & Suggestions Bug Reports
1

Description:
Left-click detection fails when JangaFX applications are maximized, causing nodes to shift position when selected and numeric input fields to trigger slider behavior instead of allowing direct text editing. The issue affects all three products (EmberGen, LiquidGen, IlluGen) I use from JangaFX but only occurs in maximized window mode.

Steps to reproduce:

  1. Maximize any of the JangaFX applications (EmberGen, LiquidGen, or IlluGen)

  2. Open any project with nodes in the node graph

  3. Left-click on any node to select it

  4. Observe that the node shifts position slightly (down and right) instead of just being selected

  5. Navigate to any numeric parameter field in the Node Details panel

  6. Left-click on the numeric input field attempting to edit the value directly

  7. Observe that the value changes instead of the field becoming editable for text input

Expected behavior:

  • Nodes should select without moving position

  • Numeric fields should highlight for direct text input when clicked

Actual behavior:

  • When maximized: Nodes shift position 80-90% of the time when clicked, numeric fields trigger slider drag behavior instead of text editing

  • When NOT maximized: Application behaves correctly with proper left-click detection

Additional info:

  • Affects all three products: EmberGen, LiquidGen, and IlluGen

  • Occurs on Windows 11 with current versions (as of 9/21/2025)

  • Issue persists across previous versions tested over last two months

  • CRITICAL: Bug only occurs when application window is maximized - windowed mode works correctly

  • Attempted AutoHotkey solutions do not resolve the issue

  • Reproducible 80-90% of the time when maximized, 0% when windowed

Hey thanks for reaching out about this. I see the issue in your screen recording but it doesn’t behave the same for me. Can you enable mouse compatibility mode in the preferences and disable Smooth UI if its enabled?

If that doesn’t work please send me a screenshot of your preferences just so I can get an idea of what could help in troubleshooting this.

Thanks for your reply! The attached image shows the settings from the “General” section of my preferences.

A few notes:

  • The “Mouse Compatibility Mode” was originally enabled but even upon disabling it & restarting the application there’s no change.
  • I’ve never had the “Smooth UI” option (knowingly) enabled afaik.

Anyway, thanks again for the assistance!
