Summary: Some shaders result in splotchy patches of color
           Product: Wine
           Version: 1.3.11
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Some shaders (they seem to be blur ones, could a specific kind of 'soft' blur,
depth of field blur or maybe even HDR lighting) instead of bluring, regions of
splotchy fuzzy colour are produced.

I have noticed this in both "Mirror's Edge" and "The Ball".

I am running on a Nvidia GTX260, with the official proprietary 260.19.06
drivers.
Ubuntu 10.10 x86_64

In Mirror's Edge it happens when you look into a dark area after looking at a
bright one for a while (or maybe it's when you stare at different colours such
as bright red followed by a dark area). There is supposed to be a kind of blur
effect that fades fairly quickly. Screen shots from the 'prologue' level after
the jump gap onto pipes and enter the door.

on the screenshot, but there is a subtle soft blur effect that fades away quite
quickly).

In "The Ball" it's noticeable a bit on the title screen, but when underwater it
becomes most obvious. Screenshots from the 2nd level.
