Rhino 7 text mask problem

This was never fixed in R6.

That is correct. Text masks do not work well with perspective projections. We will probably need to rewrite how masks are displayed using different techniques to solve this issue in the future.

It’s strange, 'cause if I use BringToFront on the text - it draws properly.

That is because send to back and bring to front geometry is drawn without depth testing. We can’t do that with text drawn in its normal mode.
