[Linux]: Depth testing is not working creating more than 8 entities with a QPlaneMesh set on them

[Linux]: Depth testing is not working creating more than 8 entities with a QPlaneMesh set on them. What happens is that the ones that are created after the 8th is that they end up being seen over the ones that should appear first.

In the example attached, when you move the slider up to 8 then just white ones show up which is correct. Once you go past 8 then they will all appear as black although it should be just shown as white.
