Infinitely Expanding Window, Potential BSoD on Hook - Xuan-Yuan Sword: The Gate of Firmament (Steam)

[anchorlightforge]

Bug:

• Remix will hook to the game Xuan-Yuan Sword: The Gate of Firmament then expand and reinitialize the window rapidly.
• When the window grows past a certain size, Windows will crash and return a blue-screen. Until the system or application stops, the application will seemingly behave as normal despite the steady resolution changes.
• According to the logs, the window increases in width and height by 50 pixels every change in the affected XYS games. This can vary depending on the title affected, such as Shadowrun Returns where only the width is affected by an error of 10px.
• This bug only occurs in windowed mode. Affected applications will start without error in fullscreen.
• This behavior has been observed in multiple engines and in games by multiple developers.

Environment:

• Build: Bridge Remix 4d6dc56-6, DXVK Remix 72c4d36-90 and fe511a5
• GPU: Nvidia Geforce RTX 3080
• Drivers: Nvidia Studio Driver 531.41
• Known Affected Applications:
  • Shadowrun Returns - Unity 4.2.0f4 (GOG, current release build) (only grows in width, not height; occurs on startup)
  • Xuan-Yuan Sword: The Gate of Firmament - Unity 5.0.2f1 (Steam, current release build; occurs on startup, can induce BSoD after some time)
  • Xuan-Yuan Sword: The Clouds Faraway - RenderWare (Steam, current release build; occurs on in-game resolution change)
  • Xuan-Yuan Sword: The Cloud of Han - RenderWare (Steam, current release build; occurs on in-game resolution change)
  • Deus Ex: The Fall - Unity 4.3.4f1(Steam, current release build; occurs on startup)

Logs:

• NvRemixBridge.log: NvRemixBridge.log
• d3d9.log: d3d9.log
• Game log: SWD6E_d3d9.log

  Note: These logs are from a session where the application was force-closed before a BSOD could occur.

To Reproduce Steps to reproduce the behavior:

1. Open the game and make sure that Windowed mode is enabled in the settings.
2. Set up Bridge and DXVK Remix in the game's EXE folder.
3. Open the application.
4. The window initializes successfully at a default resolution of 1280x720, then grows by 50 px in width and height incrementally on repeat until the application or the system crashes.
   • In some cases, the application will stop early and begin normal operation at its larger-than-intended resolution.

The log (example from Shadowrun Returns) will report an infinite loop of the following functions:

d3d9_device.cpp:7513: D3D9DeviceEx::ResetSwapChain ->

• rtx_resources.cpp:744: Resources::createDownscaledResources(Rc& ctx) ->

  • rtx_resources.cpp:990: Resources::executeResizeEventList(ResizeEventList& eventList, Rc& ctx, const VkExtent3D& extent)

• rtx_resources.cpp:939: Resources::createTargetResources(Rc& ctx) ->

  • rtx_resources.cpp:990: Resources::executeResizeEventList(ResizeEventList& eventList, Rc& ctx, const VkExtent3D& extent)

D3D9DeviceEx::ResetSwapChain:
  Requested Presentation Parameters
    - Width:              2900
    - Height:             1071
    - Format:             D3D9Format::A8R8G8B8
    - Auto Depth Stencil: false
                ^ Format: D3D9Format::D24S8
    - Windowed:           true

Render resolution changed, recreating rendering resources

Target resolution changed, recreating target resources

D3D9DeviceEx::ResetSwapChain:
  Requested Presentation Parameters
    - Width:              2910
    - Height:             1071
    - Format:             D3D9Format::A8R8G8B8
    - Auto Depth Stencil: false
                ^ Format: D3D9Format::D24S8
    - Windowed:           true

Expected behavior The window should initialize at the selected resolution and maintain this resolution.

• @Aelthien observed that enabling the "Allow Resizable Window" flag in the Unity Editor will allow a newly built Unity application to reset the swapchain correctly. (tested with Unity 2017.2.5f1, just before D3D9 support was removed)

I've now confirmed that this behavior also occurs with XYS: The Clouds Faraway if you attempt to change resolution in-game.

[anchorlightforge]

This bug can also be reproduced in Shadowrun Returns (GOG). It manifests differently with only width affected instead of width and height, and at a slower rate-- but the log references the same functions that were returned in the original bug report.

Also occurs with Unity projects built in 2017.2.5f1

Hello! Will you please test this on the latest release and let us know if the issue persists? Thank you!

[anchorlightforge]

@NV-LL I can confirm that with 0.5.0 release this bug still occurs. I noticed that it did not occur on launch this time, so I can't guarantee that it's not a different bug with the same impact. To reproduce:

1. Open an affected game-- the one above will work, any Unity game where the window is not resizable will also work.
2. Change the resolution in-game.
3. The window will infinitely expand, though some games eventually stop growing and begin to function again at a higher-than-intended resolution.

For convenience I have also included a video @Kim2091 created of a Kerbal Space Program alpha build where this issue occurs. This is a much earlier version of Remix and a different title in the engine, but the issue is identical in impact.

Hi @anchorlightforge , is this issue distinct from issue #499 at this point, or are they duplicates of each other?

[anchorlightforge]

@nv-ajaus It's somewhat related and most likely the same issue. I posted separate issues because we were instructed to do so for a similar cascading issue that affected multiple titles. If desired I can close the latter of the tickets.

The main difference is that in this ticket, the engine's built-in behavior for resolution switching and initialization in windowed mode will fail without certain flags enabled in-editor, while with the latter tickets the developers' implementation of resolution toggles in windowed mode triggers the same issue.
