Bug ID: 49518
           Summary: Grim Dawn leaks shared memory after upgrade to Wine
                    5.12
           Product: Wine
           Version: 5.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

After a few hours of gameplay Grim Dawn consumes around 10 GiBs of shared
memory, as reported by KDE System Monitor (KSysGuard). At that point the game
stopped running because of:

err:   DxvkSubmissionQueue: Failed to sync fence: VK_ERROR_DEVICE_LOST
err:   DxvkSubmissionQueue: Command submission failed: VK_ERROR_DEVICE_LOST

The game audio continued to play and it sounded like it was reacting to
keypresses, but the display image was frozen.

I'm not sure what kind of memory is reported as shared memory, but given that
it ends with a DXVK error, it looks like it may be GPU memory.

This did not happen with Wine 5.10.

Kubuntu 20.04 x86_64, Nvidia driver 440.66.17 (RTX 2080 Ti with 11 GiB VRAM),
DXVK 1.7.
