And, in addition [[bugzilla:26967]] should be related to this one. Patch
db8d681a5b088b3b0dd58c6952086891f6bbb4f5 broke water shaders if shaders are set
above low.
I opened 2 Bugreports for Nvidia (
http://nvnews.net/vbulletin/showthread.php?p=2445516 ) as well as ATI (
http://ati.cchtml.com/show_bug.cgi?id=160 ) unfortunately I am not a pro at all
when it comes to graphical issues but I tried my best ;) So if any of the wine
developers who actually know what the issue is exactly and how the driver
vendors could fix it (e.g. by providing an extension with witch the d3d
floating point behaviour could be defined) may post there and help fixing the
issue.

Btw it seems as if it got fixed in dx3d 10 as mentioned here:

"Honored IEEE-754 Rules

Some of these rules are a single option where IEEE-754 offers choices.

Divide by 0 produces +/- INF, except 0/0 which results in NaN.
log of (+/-) 0 produces -INF. log of a negative value (other than -0) produces
NaN.
Reciprocal square root (rsq) or square root (sqrt) of a negative number
produces NaN. The exception is -0; sqrt(-0) produces -0, and rsq(-0) produces
-INF.
INF - INF = NaN
(+/-)INF / (+/-)INF = NaN
(+/-)INF * 0 = NaN
NaN (any OP) any-value = NaN
The comparisons EQ, GT, GE, LT, and LE, when either or both operands is NaN
returns FALSE.
Comparisons ignore the sign of 0 (so +0 equals -0).
The comparison NE, when either or both operands is NaN returns TRUE.
Comparisons of any non-NaN value against +/- INF return the correct result.
"

I hope I could help a little :)
