           Summary: Linux Mint, X11, nVidia, 200% scaling reverts to 100%
                    scaling on Screen Res Changing
           Product: Wine
           Version: 9.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

Mint 22.2 Cinnamon
NVidia 575 Open Drivers
WINE 9.0 from the built in repo has been used.

I have been testing thing in Mint 22.2 Cinnamon and noticed that my 4k screen
requires 200% DPI to make it readable, this lets WINE run fine. I am able to
use 100% or 200%, but after a game changes to 800x600 or 640x480 etc, when it
changes back to 100% Scaling on me, even though it was set to 200% when I
executed the game, I understand why it does this during gameplay, but it should
remember and revert my old Scaling option where possible. I also understand
this is only one Desktop Environment on one Distro, but I have had it have
other issues, I'll just mention them here as I don't expect them to be fixed as
it's Cinnamon issues and not a Wine, you guys shouldn't be the ones to make
work around's to issues like these. But if you happen to, I don't mind who
repairs it as I would like it to change itself back to 200% when Wine is done
if it gets changed by the WINE app or at least while the WINE app was running
but has exited, I do know that if 2 wine games or apps were running, you would
have to leave it set to 100% until both have ended, so understand it's not
straight forward to fix.

If I use Wayland it doesn't change screen resolutions at all, xrandr isn't even
available and the alternatives they offer are not very capable for me to script
it for games that require it (Multi system, I can do my current system, but it
doesn't have a default display, you have to provide the output port, HDMI, DP,
RGB etc). I found using Steam to execute them works fine, will change the res
and stretch to fit the screen. Even though WINE is able to run them, it puts
them in a 800x600 or whatever res it is meant to scale, on the top left of my
4k display (set to 100% or 200%). Using Nouveau drivers for nvidia or MESA on
AMD cards works fine and scales. so I just chalk this up to NVidia issues. But
I use my system for LLM's, AI Gen and need the Cuda drivers and 3D acceleration
to achieve this, so that's not an option.

Thanks for all you do.
