VSlider knob clips at top and often also at the bottom

[saurik]

This is visible in the imtui online demo (so it should be easy to see): if you go under Widgets / Vertical Sliders the sliders have knobs that are 2 rows tall, except when at the very top they are being rendered as one row tall... but clearly with the space where the second row would be being rendered, so it isn't like it is somehow off the top of the slider or anything. Some of the sliders (the ones towards the left) are exhibiting the same behavior at the bottom.

Thanks for the report.

You should be able to fix this visual artifact using:

ImGui::GetStyle().GrabMinSize = 1.0f;

By default, the value is 0.1f:

imtui/src/imtui-impl-text.cpp

Line 266 in 85d141d

ImGui::GetStyle().GrabMinSize = 0.1f;
