Bug ID: 48920
           Summary: Can't quit Legends of Runeterra by closing virtual
                    desktop window (stack overflow) (5.6 regression)
           Product: Wine
           Version: 5.6
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

In wine-staging-5.5, when running Legends of Runeterra in a virtual desktop,
you could close the game by clicking the X button on the virtual desktop's
window. The game would close, and then shortly afterwards the virtual desktop
would close.

In wine-staging-5.6, when you click the X button on the virtual desktop, the
game does not close, the virtual desktop does not close, and the following line
is printed in terminal output:

0052:err:seh:setup_exception stack overflow 1600 bytes in thread 0052 eip
000000007bce1e27 esp 0000000000120fd0 stack 0x120000-0x121000-0x220000

(The thread number changes, but all other values seem to be consistent between
attempts.)

Quitting the game using the in-game menu works fine.

Gentoo, x86_64

I'll work on getting a regression range
