Bug #: 31952 Summary: Graphical bug causing horizontal lines on world Product: Wine Version: 1.5.15 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: jonathan-vola@hotmail.com Classification: Unclassified
Presumably due to a texture being projected horizontally, several areas in game have horizontal "Slices" in them.
This was to my knowledge added by an update to the game not to wine, so there is (probably) no regression.
Some areas where this bug is blindingly obvious are north Diessa Plateau and west Rata Sum.

--- Comment #2 from J V jonathan-vola@hotmail.com 2012-10-13 05:08:42 CDT --- Some more testing shows that setting textures to low affects the surrounding textures but not the lines, they remain perfectly 1px thin.
Lines become thicker depending on sampling: Supersampling provides thin lines as in screenshot, subsampling provides thicker lines.

Let me think... Do you have an AMD card?
Nope, this was taken on an nvidia GTX 680.
The effect doesn't happen everywhere, only at certain parts.
Also, I am not the only person with this bug, it's been discussed on the forum thread about GW2 ( http://forum.winehq.org/viewtopic.php?f=2&t=15121&start=150#p800379 )

Try turning off any anti alias settings you have set in nvidia-settings, doing this for me stops the lines forming. so choose "let application decide" and they should go away.

--- Comment #7 from Austin English austinenglish@gmail.com --- This is your friendly reminder that there has been no bug activity for over a year. Is this still an issue in current (1.7.37 or newer) wine? If so, please attach the terminal output in 1.7.37 (see http://wiki.winehq.org/FAQ#get_log).

--- Comment #8 from Ahmed W. oneofone@gmail.com --- I can confirm this bug is still happening with wine 1.7.41 (with AND without wine-staging).
@Kitty, that doesn't change anything for me.

--- Comment #9 from Guillaume R guillaumeraffin@free.fr --- This is a problem I also had in Windows (windows 7 SP1). Do you have an integrated graphic chip ? (intel ?) If so, try to force the game to run with the graphic card, for example using Bumblebee and the "optirun" command. I removed this problem by doing so.

--- Comment #10 from Anonymous winehq72@mailcatch.com --- I had the same problem on Nvidia GTX 770 using nvidia binary drivers and wine 1.7.49 staging (CMST enabled, i didn't test without it). Turning off anisotropic filtering and texture sharpening in the nvidia control panel helped for me (normally i have them enabled).
I already encountered something similiar in Dishonored, which would show a one pixel thin reddish outline around every object. It was very distracting (and FXAA didn't help), but i found that it was also caused by having anisotropic filtering forced in the control panel.
Both games offer only shader based FSAA, so my guess would be this has something to do with their lightning implementation interfering with wine and anisotropic filtering. Hopefully whis workaround will help others.
Btw, why is this still UNCONFIRMED after users confirming it for almost 3 years?

--- Comment #11 from Matteo Bruni matteo.mystral@gmail.com --- This sounds like INVALID or maybe NOTOURBUG. Forcing specific texture settings via nvidia-settings or similar driver tools might not work correctly with some games and that's clearly the case here.

--- Comment #12 from Anonymous winehq72@mailcatch.com --- The same problem does not occur on windows, so it is not caused directly by a bug in these games but by an interaction with wine.
It is very common for people to just turn these settings on and forget them, since this is the only way to get improved graphics in old games and they usually have no/negligible impact on performance.
If it is confirmed that the anisotropic override is the cause, it would be interesting to check if the problem is caused by particular implementation in the driver/nvidia-settings, or if it is caused by anisotropic filtering itself. In the second case it could cause problems in newer games where anisotropic filtering cannot be turned off (and which are more likely to use deferred shading or similiar methods).

--- Comment #13 from LingM lingm+winebz@posteo.org --- Looking at the screenshot, this is the same problem as I reported against dxvk in Nov 2019. https://github.com/Joshua-Ashton/d9vk/issues/450
Debugging that, it turned out to be a rounding issue affecting at least amdvlk, radv, radeonsi, r600, and the AMD Windows OpenGL driver.
Fixes to the open source drivers landed mid 2020: amdvlk: https://github.com/GPUOpen-Drivers/xgl/pull/49 radv: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/3951 radeonsi: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/3953 r600: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/5078
Some were backported to stable releases, some weren't, but as of Mesa 20.2.0 all the Mesa drivers should be fixed.
We were unable to reproduce on Nvidia cards, so if they really were affected in the past, it was probably fixed somewhere in the 7 years since this bug was opened.
Can somebody please close this as NOTOURBUG?
