The bug is that the hitbox of the slider is not on the same camera as the slider itself.
This issue seems to have been fixed in a Psych Engine pull request, shadowing the class here
It happens with both FlxSlider and FlxUISlider and I've tested on HashLink and C++ targets.
I've put together a little demo of the issue here
FlxG.camera.zoom = 1;
FlxG.camera.zoom = 0.5;
I'm not sure if this is a known issue or not but I couldn't find anything about it besides the Psych Engine pull request.
