Unfortunately, holding Shift doesn’t help. I tried Shift before, Shift after picking up, nothing happens
Yeah this is a known Unity issue. I'm not sure what I need to do to address it. I'm using the new fangled Input System-- and on Linux it doesn't read mousewheel inputs the same way it does on other platforms. I'll make an issue on git so I can keep track of it and hopefully I'll come up with a solution that doesn't involve writing linux-specific code.
