Bug ID: 43849
           Summary: Heroes of the Storm; crashes when Call Mech effect is
                    on-screen
           Product: Wine
           Version: 2.18
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Steps to reproduce:
Start Heroes of the Storm.
Enter Try mode with D.Va.
Take tower damage until your mech is dead. 
Shoot enemies until your Call Mech cooldown is activated.
Use Call Mech 'E'.

The mech arrival effect will begin but the game will crash before the mech
becomes visible on-screen. A dialog box pops up with a
e_gfxerrorshadercompilefailed error.

Relevant wine stdout:

I experimented with 
winetricks d3dx9_43 
but that didn't fix the crash (it does change the error signature).

I also tried 
d3dcompiler_43 (native) 
but it didn't seem to matter.
