Bug ID: 55618
           Summary: incorrect monitor resolution
           Product: Wine
           Version: 8.0.2
          Hardware: x86-64
                OS: Linux

Inquire wine graphic resolution

$ dpkg -l | grep wine
ii  wine-stable                                    8.0.2~trixie-1
ii  wine-stable-amd64                              8.0.2~trixie-1               
ii  wine-stable-i386:i386                          8.0.2~trixie-1

I have a dual monitor configuration with Xinerama/NVidia:

Screen 0: minimum 8 x 8, current 1920 x 1200, maximum 16384 x 16384
DP-0 connected primary 1920x1200+0+0 (normal left inverted right x axis y axis)
432mm x 324mm
   1920x1200     59.95*+
Screen 1: minimum 8 x 8, current 1600 x 1200, maximum 16384 x 16384
DP-1 connected primary 1600x1200+0+0 (normal left inverted right x axis y axis)
408mm x 306mm
   1600x1200     60.00*+

Wine reports the resolution as 1024x768 and I cannot scale a graphic wine
window past that. This change happened only in the last 2 months, this bug was
not present on the same machine with same Xinerama/NVidia configuration.
I'm not able to make this work again because kernel and a lot of libraries have
changed since. Simply rolling back the wine version did not solve this bug.

The attached program incorrectly reports the screen resolution as 1024x768 with
both methods.

After spending a day trying to fix this I've ended up binary patching the
following files (I wasn't successful at build wine from sources):
            lib/wine/i386-unix/win32u.so
            lib64/wine/x86_64-unix/win32u.so
I have patched the add_monitor' 'get_display_rect' & 'get_primary_monitor_rect'
functions from the above libs so that monitor->rc_monitor and monitor->rc_work
are (0,0,1920,1200)

Now the reported resolution with both methods is 1920x1200 and all the wine
programs work correctly.

This seems specific to your machine. Could you do a bit more debugging to see
where the 1024x768 is coming from? Also, a +system,+randr,+x11drv log would be
helpful.

I've added a trace log.

What's in the output of `xrandr --verbose`?
