Description

From the image rendering checklist by Shuhuan Xiao.
OS: Ubuntu 22.04.1 LTS

I'm unable to recreate this on Ubuntu 22.04.

Checklist Item
Use the DataManager to turn „rgbImage“ visible and „ramp“ and „rgbaImage“ invisible; test the LevelWindow

Expected Result
Only the image „rgbImage“ is visible and the displayed color range changes in accordance with the setting of the LevelWindow Slider.

Observed Result
Also after sliding the LevelWindow Slider around too many times at extreme ranges makes MIT K crash :(

I recreated the problem by loading any image (the described ones work, as well as just Pic3D.nrrd) and moving the level windows really far (either by dragging the bar to one direction, or moving it back and forth to the upper and lower bounds), to values around the scale of 4e+38. At that point, the workbench just freezes and stops responding.
