Bug ID: 57422
           Summary: Winecfg DPI issue with games
           Product: Wine
           Version: 9.21
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

I have an NVIDIA card and a 4k screen

To make my wine apps readable I use winecfg Graphics tab and set the DPI to
192, which works great for windowed desktop apps, but as soon as I run a game,
it only shows the top left of my game and crops the mouse area even smaller
than that. I changed the DPI back to 96 (default) and they work as
expected/intended.

This even occurs if I use a virtual desktop.

The other issue with 4k screens on NVIDIA  is it can't mode set at all, I need
to preset the mode using xrandr and pass the new res to the virtual desktop. If
I leave it to change the mode itself, 8 get a black screen and it powers the
screen off. I can get the terminal back by pressing ctrl + alt + F2. Or get the
login screen with ctrl alt backspace. But nothing else I do can change the mode
back or turn the screen back on.

So to be clear, I need to sety wine DPI to 96dpi and preset my screen res to
run games (full screen). I do not get the same issue on my NVIDIA graphics
laptop and I don't on AMD graphics. Just my 3060to and a 4k screen.

I no longer have a 1080p screen to test if that works. But changing my desktop
to 1080p doesn't fix things except for games that are 1080p. 800x600 and
1024x768 will cause the black screen issue.

I noticed that wine v9.0 (mint v22 default) doesn't have the doi glitch 9ny 4k
screen. It does still have the black screen bug if I don't pre modest.

I use NVIDIA v550 drivers

Nouveau does not have these issues at all. So I hope something can be done for
wine to recover from this black screen crash or failed mode sets. I do not
expect wine Devs to fix the NVIDIA bug... Would be happier if you could. But I
know how hard NVIDIA have made things in Linux. I hope their latest promises
and open sourced kernel modules improve it soon. But crash prevention for now
would be awesome, I sometimes forget to mode set and have to lose unsaved work.
