Tick icon and Keyboard layout flashing on screen when loading content with screen overlay and controller connected with D3D

[sonicsheppard]

First and foremost consider this:

• Only RetroArch bugs should be filed here. Not core bugs or game bugs
• This is not a forum or a help section, this is strictly developer oriented

Description

There is a large 'tick' icon, followed by a fullscreen keyboard layout image which very briefly flashes on screen when loading up any content with any libretro core. This is seemingly only happening when using a D3D10, D3D11 or D3D12 graphics backend (not D3D9), combined with an onscreen overlay and with a controller connected.

I have found the issue does not occur if there is no onscreen overlay enabled, or the controller is not connected on launch (I'm using a Bluetooth XBox One controller), or a different graphics API - tried with opengl and Vulkan.

Expected behavior

No 'tick' icon and keyboard layout flashing on screen when launching content.

Actual behavior

Large 'tick' icon flashes on screen, followed by a large keyboard layout flashes on screen when using D3D graphics backend, a Bluetooth controller connected and an onscreen overlay enabled.

Steps to reproduce the bug

1. Install latest version of Retroarch (currently 1.8.4)
2. Download a core (e.g. PicoDrive)
3. Set the Video backend API to D3D12 and save the config.
4. Open the PicoDrive core with any content and enable and save an onscreen overlay - e.g. a 32x border for 4:3.
5. Connect a Bluetooth controller to your Windows 10 system (Xbox One controller).
6. Launch the core with content, with the API set to D3D12, the Bluetooth controller connected and the onscreen overlay enabled.

Bisect Results

I have rolled back to previous Retroarch versions and it is occurring on the previous 4 versions I have tried.

• OS: Windows 10
• Intel NUC i7
• Integrated graphics Iris 655.

Same exact problem. This flashes several times when I start a ROM. To me it happens without having any controller connected (besides the keyboard and mouse).

Same on me, when i use d3d11 and any overlay, i have a keyboard overlay flashing now and then.
