Incorrect position in OpenMW (OpenGL)

[rharish101]

My MangoHud config is the default one, with the position set to top-right as the only change. When I open OpenMW, which uses OpenGL, MangoHud is shown in the middle-left as opposed to top-right.

My setup:

• OS: Arch Linux
• MangoHud version: 0.3.0 (from the AUR)

The underlying problem seems to be that openmw is not giving the correct GL_VIEWPORT, it's always set to 800x600. I think this is something that should be fixed in openmw

Thanks, I'll raise the issue there.

It's not always set to 800x600, just when the buffers are swapped. We're not explicitly doing this, OpenSceneGraph is. More details here: https://gitlab.com/OpenMW/openmw/-/issues/5312#note_315016884

I'm bumping this again as I've been tidying OpenMW's issue tracker. From our perspective, either MangoHud is incorrect to assume the full viewport is set right before the buffers are swapped, or OpenSceneGraph is incorrect to set a default viewport size right before swapping buffers. This is something that needs to be discussed between the MangoHud developers and OpenSceneGraph developers, as the problem will exist for every OSG application, so there's not any particular need for the OpenMW team to get involved.

To recap, OpenSceneGraph resets the OpenGL state to what it views as a reasonable default at the end of every frame. That includes setting an 800x600 viewport, regardless of what the default framebuffer's size actually is.

It doesn't appear to be an issue anymore, most likely fixed on our end a while back

Cooleo. I'll close the issue on our tracker.

Yes, sorry, this was fixed sometime back.
