Just an observation, I've noticed that 1U modules are looking rather weird right now with either end of their graphic being cut off.
Please look into this!
Regardless of their name 1U tiles don't necessarily share the same height. ModularGrid uses the specs from PulpLogic. They differ slightly from Intellijel 1U modules. For that reason the module graphics for Intellijel must be padded top and bottom in an image editor before uploading them to MG.
E.G. an Intellijel 1U module graphic must be cropped like every other module. After that the image canvas height must be multiplicated with a factor of 1.082.
It seems that Intellijel has uploaded new versions of their modules without the needed padding. I hope that will be fixed, until that you can still use the old images by using the Panel Selector feature:
