Bug #: 31235
           Summary: League of Legends minimap corrupted
           Product: Wine
           Version: 1.5.8
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

While running League of Legends (either using a compiled, patched 1.5.8, or
using PoL 1.5.5-league) the minimap is corrupted (it is there, but something
else/blocky is being drawn over it.

I can workaround it in game, but turning vsync on/off multiple times until it
clears.  This must be done for each game, so can be a very annoying workaround.

No idea if this is graphics/driver/or wine related, so not sure what logs/ect
would be most helpful.

I'm new to wine/linux - so any requests for data would be faster if the actual
command lines to attempt to run are given.

running Intel I5-3570k
listed graphics is VESA:CYPRESS - but it is GIGABYTE GV-R585D5-1GD-B Radeon HD
5850 (Cypress Pro) 1GB 256-bit GDDR5 
os ubuntu 12.04 lts 32-bit (I might try 64 bit sometime after people stop
talking about bugs/regression related to it)
