| different bgfx transient buffer issue (dx11) | |
| Reproduction steps: | |
| 1. use Direct3D11 renderer | |
| 2. in each frame: | |
| 2.1. render anything (even single vertex) with one vertex decl | |
| 2.2. render some triangles (or other geometry) with different vertex decl | |
| some additional comments in the code | |
| (the dx shaders are compiled with vs/ps_4_0 profile) | |
