[bisected] Black screen when using multimonitors, works with only one monitor

[sarnex]

Hi all,

I am running into a bug when using wine from iXit/wine and multimonitors.

The demo app is textured_quad.exe from: http://www.drunkenhyena.com/cgi-bin/view_cpp_article.pl?chapter=2;article=30

GPU is Vega 64, using Mesa git and Kwin.

I have two monitors.

I bisected this to: https://github.com/iXit/wine/commit/3304969be6d8be1d109e82f66d95aa4bc472f0f3

Of course, wined3d9 works in all cases.

1: Log with two monitors (black screen in app): https://paste.pound-python.org/show/kgYNnQoMaz9IIdVscVNH/

2: Log with working image using old version of my patches: https://paste.pound-python.org/show/GhJ5CqHNfoECPzeCCfat/

3: Log with new patches but second monitor disabled (correct image in app): https://paste.pound-python.org/raw/XyGGEqk5LWqGheiEYaYt/

Diff between 3 (left) and 1(right): https://www.diffchecker.com/hiGM2KRX

Please let me know if you have any ideas or patches.

Thanks, Sarnex

I'm hitting the same issue, seems to be something with the presentation. The picture is offset in x and y by something like 10px on one monitor, but when I'm running my usual setup with 3 monitors, the whole screen is black. So it's probably being drawn, but just not in the right place.

Same bug as reported in iXit/wine-nine-standalone#3, which I fixed over there with https://github.com/iXit/wine-nine-standalone/commit/f286909a92573dcadb8bcc1586108154711936f2

I rebuilt wine-nine-standalone and can confirm this is fixed. Thanks :+1:

@dhewg Thanks, can you backport this to here? I need to use this repo to generate my patches.
