Mangohud capture not working (doesn't show or flickers) on Control DX12 after intro movies

[mmbossoni]

I've first noticed this with Lutris flatpak on Nobara, but confirmed with Heroic on Arch as well Capture starts fine and shows Mangohud and game. After intro movies, reaching game menu, Mangohud capture stops. If game stays on background (0fps?) it shows again, but interacting with game make it disappear

Interesting, using another issue workaround for ordering seems to make things work VK_ADD_LAYER_PATH=/usr/share/vulkan/implicit_layer.d VK_LOADER_LAYERS_ENABLE=VK_LAYER_OBSvkcapture*

[nowrep]

So, it's fixed now? :)

[mmbossoni]

Only if I force this ordering stuff. In that case I get Application -> Loader -> Mangohud -> vkcapture -> Device

When layers are In the case I get Application -> Loader -> vkcapture -> Mangohud -> Device it doesn't work (Dx11 applications never show it, dx 12 show it flickering). Don't know which is the proper ordering.

Probably same thing as https://github.com/nowrep/obs-vkcapture/issues/14?

[nowrep]

Yes, the ordering here is important.

[mmbossoni]

@nowrep , just for peace of mind: vkcapture should always be near device?

[nowrep]

It depends on if you want to capture other layers (mangohud) or not. So in this case, "near device" means it will capture what you see on the screen (including mangohud overlay).
