UI Builder slider value lags and stutters when sliding/modifying certain property values

UI Builder

-

Steps to reproduce:

  1. Create a new Unity project using the Universal 3D template
  2. Go to Project Settings > UI Toolkit > Text
  3. Enable "Advanced Text Generator"
  4. Create a new UXML document and open it in UI Builder
  5. Add a Label to the Hierarchy and select it
  6. In Inspector, expand the Text or Transform foldouts
  7. Change "Text Generator Type" to Advanced and enable "Auto Size"
  8. Hover next to Min or Max value and hold the left mouse button and drag to change the value
  9. Observe the value change

Actual results: The Min/Max value changes in a laggy/unsmooth way while dragging and continues to change even after the mouse button is released, sometimes updating just from moving the cursor in UI Builder

Expected results: The Min/Max value changes smoothly in small increments while dragging and immediately stops changing once the mouse button is released

Reproducible with versions: 6000.0.66f1, 6000.3.7f1, 6000.4.0b6, 6000.5.0a5

Tested on (OS): Windows 11

Notes:

  • This could be very machine or environment-specific, and sometimes does not reproduce after the machine is restarted or etc. However, once the issue appears, I found it only affects fields in "Text", "Border", "Transition Animations" and "Transform" foldouts, other fields do not seem to lag
  • Likely not caused by enabling "Advanced Text Generator" as the issue also reproduces on 6.0 where the option is not available; however I found that its the fastest way for me to reproduce the issue
  • Once the issue reproduces, the value is modified even when not using the slider, but just moving the cursor through UI Builder
