I came back to this PR and tested this after merging with `gz-sim7`. It's working for me on Ubuntu Focal and macOS. Here are some general notes on testing gz-sim...

Thanks for dropping the notes on macOS issues. I'll create a ticket to track them > I can force push a rebase against 942da23 if that makes things cleaner? that...

one thing to try on Fortress is to launch ign-gazebo with the `--headless` arg, which asks it to use EGL instead of X, and see if that makes any difference.

I just tested this but was unable to reproduce either. @EvilPictureBook what graphics card and driver are you using? Do you have a high dpi display?

I remember @jennuine mentioned that fractional scaling has to be enabled and the scaling factor needs to be at 100% for things to work properly. Just checking, do you have...

@dignakov, can you give this patch a try? ```cpp diff --git a/ogre2/src/Ogre2Camera.cc b/ogre2/src/Ogre2Camera.cc index 86d1d7b9..b5043a52 100644 --- a/ogre2/src/Ogre2Camera.cc +++ b/ogre2/src/Ogre2Camera.cc @@ -259,7 +259,7 @@ VisualPtr Ogre2Camera::VisualAt(const ignition::math::Vector2i &_mousePos) this->ImageWidth(), this->ImageHeight());...

playback scene broadcaster issue should be fixed in [f4728cc](https://github.com/gazebosim/gz-sim/pull/1636/commits/f4728ccccaeba0c39b9ee6fec56dbadaff99df9e). Now if no periodic changes are available when scene broadcaster is publishing, I force it to do an offcycle state update...

Regarding the shader compile errors: > 12:58:34: Compiler error: reference to a non existing object in selection_buffer.material(37) > 12:58:34: Compiler error: invalid parameters in point_cloud_point.material(34): incorrect type specified; only variants...

sounds like a similar problem that we ran into with Metal? So our check for anti-aliasing support is probably just not reliable. for this particular case, we could add a...
