            Bug ID: 60366
           Summary: reMarkable desktop 3.28.1 (Qt 6, D3D11): window
                    contents only update when the window is resized
           Product: Wine
           Version: 11.17
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: d3d
          Assignee: [e-mail]
          Reporter: [e-mail]
  Target Milestone: ---
      Distribution: ---

The reMarkable desktop app (x64, Qt 6.10.3, Qt Quick with the D3D11 backend)
only shows its first frame. After that the window contents never change until
the window is resized. Clicks and data loaded in the background do not show up,
so the app looks like it ignores mouse input.

Input does reach the app: +msg shows WM_LBUTTONDOWN/WM_LBUTTONUP delivered to
the main window, and the result of a click (e.g. switching the sidebar filter)
becomes visible after the next resize.

Swapchain setup according to +dxgi: CreateSwapChainForHwnd,
SetMaximumFrameLatency(2), GetFrameLatencyWaitableObject, then
Present(sync_interval 1, flags 0).

Reproduces with:
  - winex11.drv (on Xwayland) and winewayland.drv
  - wined3d renderer=vulkan and renderer=gl

Does not help: MESA_VK_WSI_PRESENT_MODE=mailbox, QT_D3D_NO_VBLANK_THREAD=1.

Workaround: DXVK 3.1.1 (native d3d11 and dxgi). With it the app updates
normally with both graphics drivers.

Steps to reproduce:
  1. Install the reMarkable desktop app 3.28.1 for Windows 64-bit and start it.
  2. Click "Notebooks" or "PDFs" in the sidebar: the view does not change.
  3. Resize the window: the new view appears.

System: Arch Linux, Wine 11.17, Mesa 26.2.3, Intel Iris Xe (Tiger Lake GT2),
Linux 7.2.6, sway 1.12 (wlroots 0.20).

This app has never been stable, but this was worst than I've seen it. Not sure
when this changed.
