Hi there,

my colleague Jan Bücken was so kind today to let me test this issue on his
card.

Graphics card: ATI Mobility Radeon HD2600
Drivers: ati-drivers-8.512 (=8.7, =8.51.3) (fglrx)

Test was done with latest wine git master (snapshot from today): last commit =
6a21ab270b2a9dc04ad38714f410e1ab27872f02

ORM is backbuffer, GLSL is disabled for the application.

Ingame settings:
PPE=medium
pixel shader skins=off

640x480: works, crop at bottom
800x600: works, crop at right
1024x768: works, no cropping
1280x800: works, crop bottom

Since this is a laptop there are no further res to test.
works in this context means: rendering doesn't have errors (apart from the
cropping issue)
Performance is good with all 4 resolutions.

Now the cropping issue is a little bit different here, see this attachment from
the other bug:
http://bugs.winehq.org/attachment.cgi?id=14271

Seems like a different clamping mode (repeat) is used here.

Now switching PPE to high:
All 4 resolutions work fine now without cropping. I didn't look that much into
the performance issue though. Going to check this again with developer mode (to
have a FPS counter).

However this verifies that the cropping is not restricted to nvidia cards, but
also happens with ATI products.

Greets,
Tobias
