Output scaling/compression issue in Linux

Hi All,

I'm trying to get this working on an Ubuntu machine, and I'm having a strange issue where the calibration print will slice just fine, but when I just test the display on the output, it's compressed to the bottom third of the print area.

As you can see from the sliced output, it looks "normal", but the graphical output from nanoDLP is compressed:

Output from HDMI from nanoDLP

I've verified that my resin profile does not have a scaling offset, and no matter what resolution I set the machine to, it always comes out like this. Please let me know if there are any files I can provide to aid in troubleshooting.

Any help would be greatly appreciated.

Checkout HDMI related configuration on pi's config.txt file.

It's a full ubuntu install on a mini pc, sorry, should have clarified that.

The desktop outputs onto the display just fine, too, it's the display window from nanodlp that has the issue.
