          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal

An AV manufacturer provides a program which generates a touchpanel UI design
which can run on a windows PC using Xpanel. There are a pair off apps (32 and
64 bit) exes, and associated dlls. These load a UI design from a .vtx file. The
design shows pages and buttons, and a simple example can swap between pages via
a button. The application will connect to an IP address/number in the
configuration menu, of the AV manufacturer controller. It will then send and
receive the state of buttons and other controls.
OS: Fedora 38 and 39. x86_64
alternatives set wine as wine64.
Startup:
- In nemo: right click Xpanel64.exe and click Wine, or
- Terminal: wine64  Xpanel64.exe
Normal Operation: (Fedora packages)
Wine 8.15 with staging
Wine up to 8.16 without staging.
Wine up to 8.16 with staging -W eventfd_synchronization.all
Fault occurs: (Fedora packages built locally using mock).
Wine 8.16 with staging
Wine 8.17 with or without staging
Wine 8.19 with or without staging
Wine 8.21 with or without staging (WineHQ Fedora repo).
Fault: Xpanel64.exe runs and shows the initial page UI. Crash occurs when
clicking a button which would normal change UI pages within the application.
Wine Debugger shows, and a second Program Error Details is available.
