            Bug ID: 58649
           Summary: SimpleTV portable (Qt5/Lua/VLC) – D3D9Ex OSD overlay
                    disappears or crashes after opening dialogs
           Product: Wine
           Version: 10.14
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: d3d
          Assignee: wine-bugs(a)winehq.org
          Reporter: riv100a(a)gmail.com
      Distribution: ---

Application tested: SimpleTV (portable fork, Qt5/Lua/VLC)
Official download: https://plst.rf.gd/?i=1

Problem: OSD overlay (D3D9Ex child window) disappears or crashes after opening
dialogs, depending on backend.

    Wayland/Xwayland → OSD appears but glitches. Dialogs do not kill it
immediately, but resizing the window often makes it vanish. Sometimes restored
by “Always on top”.
    Wine Virtual Desktop → OSD stable until "Options" dialog is opened. Then
disappears permanently (never comes back until restart).
    Xephyr (nested X11) → OSD stable until Options dialog. Opening it crashes
Wine completely.

Tested on Proton-GE 10-12/13/15 and Wine vanilla.
OS: KDE Neon (Ubuntu 22.04 base). GPU: Intel HD630 + Nvidia Quadro M620. DXVK
v2.7.x.

Expected: OSD overlay should persist after dialogs.
Actual: OSD disappears or Wine crashes.

This strongly suggests a Wine bug in handling of D3D9Ex child overlay windows.

--- Comment #1 from Rafał Mużyło <galtgendo(a)o2.pl> ---
If there are crashes, were are the logs from them ?

If the window 'disappears', did you check with xwininfo (or whatever its
equivalent for wayland is) if the window still exists, but was moved offscreen
and/or unmapped ?

logs SimpleTV



    Additional log evidence:

        When dialogs are opened, Wine spams
fixme:explorerframe:taskbar_list_SetThumbnailClip … stub!. The call fails with
0x80004001 E_NOTIMPL. At this time, OSD overlay disappears or freezes.
        DXVK shows swapchain reset to Buffer size: 1x1 right when OSD vanishes.
        Wine also prints err:win:send_erase timeout → suggests OSD child window
stops receiving events.
        Missing DLLs (WinSCard.dll, Qt5Designer.dll) are plugins, not critical.
        VLC engine logs (Invalid PCR value, h264 decode error) are unrelated to
Wine, show normal IPTV stream artefacts.

    This confirms overlay breakage is triggered by unimplemented taskbar
thumbnail clipping and D3D9Ex swapchain reset handling.
