UI Canvas not visible (but is active) in 32 bit windows build, but is visible in 64 bit build

Anyone know why a UI/Canvas wouldn’t be visible in in 32 bit windows build? The UI is “active”, it’s just not visible. If I click where I know a button should be, the action listener is evoked so I know the UI is active. The UI works as expected in other builds (Windows 64 bit and Linux). I’ve tried rebuilding a few times, no luck.

Found the problem. The parent game object of the canvas was using the Default layer instead of the UI layer. After setting the UI’s parent object to UI layer, the 32 bit windows build started showing the UI. Not sure why 64 bit windows builds didn’t have this issue though.
