System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 496.76

Blender Version
Broken: version: 2.93.4, branch: master (modified), commit date: 2021-08-31 09:23, hash: b7205031ce
Worked: (newest version of Blender that worked as expected)

Short description of error
When panning viewport in 3D paint mode with stencil mask enabled, the stencil mask disappears when moving the viewport, however does not disappear when zooming it, which indicates it's not a technical limitation.

Exact steps for others to reproduce the error

Enter 3D paint mode
Enable texture mask, select some texture and set mapping to stencil
Navigate the viewport
Result: The stencil disappears when moving the viewport, which makes it very difficult to line up stencil projection with the 3D geometry
Expected: The stencil does not disappear when navigating the view

For me, it also disappears when zooming (if you use mouse).

This seems to be by design, since this is drawn along with the brush cursor, there is a check in paint_draw_cursor (paint_cursor_is_3d_view_navigating) that returns early in case of viewport navigation (and does nothing).
I think it would be easy to still draw the texture mask (but maybe not the brush cursor) and to me it would make sense, but since this involves some kind of design decision, I would kindly ask #sculpt_paint_texture devs to comment here.
+1 from me to keep the texture mask visible while navigating.
