# Known Bugs, Issues & Limitations

<details open>

<summary>When using this with VR when the spectator control window gets moved or resized, the VR view stutters</summary>

This isn’t an issue regarding this plugin, but rather regarding how Unreal Engine's render pipeline works. Note: When you move the main window that gets initially created, the same thing happens.\
Other plugins are fighting with this issue as well.

\
**Tips:**\
Spawn the window at a specific location and don't move it, so your clients have the best non-stuttering experience

</details>

* When using this with VR, the VR view stalls while making an input and therefore having no focus
* Dragable Anywhere Causes the "On Moved" event to constantly update when moved, not just at the end
* When in a multi window, no inputs get recognized **(Currently in work)**
* "On Pressed" button events don't run instantly in a Multi Window

**These definitely need new evaluation:**

* <mark style="color:$info;">Frequent crashes when using this plugin in combination with the BackgroundBlurWithMask plugin</mark>
* <mark style="color:$info;">Loading or Unloading a sublevel causes a widget to be non functional -> You can fix this by changing the widget of the extra window to a new one or just creating the widget in the game instance so it survives level switches</mark>
* <mark style="color:$info;">UE5.5 crash: Fatal error: \[File:D:\build++UE5\Sync\Engine\Source\Runtime\D3D12RHI\Private\D3D12Util.cpp] \[Line: 991] SwapChain1->ResizeBuffers(NumBackBuffers, SizeX, SizeY, UE::DXGIUtilities::GetSwapChainFormat(PixelFormat), SwapChainFlags) failed at D:\build++UE5\Sync\Engine\Source\Runtime\D3D12RHI\Private\Windows\WindowsD3D12Viewport.cpp:310 with error 80070005 Num=3, Size=(160,28), PF=18, DXGIFormat=0x18, Flags=0x802</mark>
