Voxy rendering bugs when using freecam

When using a freecam mod to travel into Voxy blocks, a number of odd bugs occur. The most obvious one is that the vanilla chunks get "drawn over" the Voxy blocks.

Another one is that flying into the blocks will "slice" into them in an odd way; this behavior seems to be somewhat predictable, where the "slicing" changes depending on where you look. This behavior is also visible in the above screenshot, where looking down into the terrain causes it to disappear.

I am aware that this is very much an edge case, but the behavior of the bug makes me wonder if this is addressable.

Linux under Wayland, 7900XTX, using Zink (to address #214). This behavior occurs without shaders, as well as with shaders (Photon). When using Photon, I also noticed that there are some overdraw issues as well (rendering voxy chunks over transparent vanilla blocks), though that is likely unrelated.

Start by reproducing the freecam behavior on Linux under Wayland with Zink, both with and without shaders. Investigate the reported vanilla-over-Voxy drawing, view-dependent slicing, and Photon transparency overdraw; done means freecam travel no longer produces the reported rendering artifacts.
