Windows taskbar (bottom) and application options (top right) showing up when i look up and down. No posted fixes work. Need a fix, not a threat from a mod about reviving old threads.

@foxdodge That doesn't work for UWP apps such as Sea of Thieves, feel free to try it yourself. Fullscreenizer is for apps that use regular windowed/fullscreen mode, not the stupid Windows fullscreen mode. It does work, however it isn't actually fullscreen when you use it so it's kind of pointless.

This is what it looks like when using fullscreenizer on Sea of Thieves:

Edit 2:
Nice, looks like rare doesn't allow you to link images here or something even though it appears to work in the preview. I highly doubt we'll ever see a fix for this issue, though, as they clearly don't care at all.
