System information

Godot v4.1.beta1 - Windows 10.0.19045 - Vulkan (Compatibility) - GeForce GTX 550 Ti () - Intel(R) Core(TM) i3-2100 CPU @ 3.10GHz (4 Threads)

Issue description

Issue observed in:

• v4.1.beta1.official [828ec2c]

Expected behavior in:

• v4.1.dev4.official [5c2295f]
• v4.0.stable.official [92bee43]
• v3.5.2.stable.official [170ba33]

Description

A sliders mouse-over handle highlight (a circle with a ring around it) appears offset (down and to the right), the first time the mouse is moved over a slider.

Expected

The slider handle highlight, should appear on the sliders handle on the first mouse-over.
As it does in the Godot versions before: 4.1.beta1

Steps to reproduce

• open the attached project: issue, mouse over slider, handle highlight, offset.zip
  Node2D is selected, in the Scene panel, and the Transform group/section is unfolded in the Inspector panel.
• move the mouse over the Transform > Rotation, slider

Observed

The sliders mouse-over handle highlight (a circle with a ring around it) appears offset (down and to the right) from the sliders handle.

The mouse-over handle highlight moves to the slider handle when:

• the mouse is held still over the slider until the tooltip appears
• or if the mouse is moved away from the slider and back over the slider

Now the second and subsequent slider mouse-overs keep showing the handle highlight correctly.

The issue can be reproduced by deselecting and selecting Node2D in the Scene panel.
