Summary: Wine crashes computer when Shared video changes
           Product: Wine
           Version: 0.9.29.
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: wine-binary
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Affects all versions I tested from 9.27 to 9.29.

Shared video was recently changed from 32 to 64 MB.  Everything worked ok, but
more RAM was needed for main system memory, rather than graphics, so the Shared
memory was reduced back to 32MB.  However, as soon as computer was rebooted with
new Shared memory settings, wine will not run.  When wine runs, it (on this
system anyway) gives the error "libGL warning: 3D driver claims to not support
visual 0x46" 2x before the app launches, but when it launches it works fine. 
After reducing the shared RAM, it gave the error 1x, and then the system froze -
no keybd, no mouse, can't use ctrl+alt+F2 to get to console - only recourse is a
hard reset.  Took me hours (reinstalling versions of wine mostly) to figure out
the problem.  After changing BIOS settings back to 64MB shared, wine runs fine.
 I would like to be able to change the BIOS settings without Wine causing my
entire system to bomb.
