Video playback from bottom and right is missing #1

Hello and thank you for this awesome program! I have been wishing for something like this to use on Linux for a long time. I am using a Lenovo Explorer with openhmd to play videos with this and I love how fast it is. I have an issue where the video is missing from the bottom of the playback and from the right side. I'm attaching a couple screenshots and used the youtube example from the readme to create them.

output from playing video bottom missing: Screenshot_20210116_162619

output from playing video right side missing: Screenshot_20210117_224112

The offset between the eyes, if that is the correct term, is off when playing the youtube video but other local files I have work just fine. It makes it look like double vision in my headset.

hmm, probably because I'm just using a cube to map out the video, should be a sphere I guess (what it is doing is just rendering the video on a cube, and then two render passes from two different perspectives, ish).

I think what this really should be doing is rendering in two passes using shaders, one just to "unpack" and then one for each eye.
