No, I am not using the DoubleWide addon.
To verify the conflict, I only had LightHeaded and Carbonite loaded.
Note:
The LightHeaded alignment issue is only temporary, each time the Quest window is launched. The following actions will correct the misalignment:
- Hiding/Expanding the LightHeaded panel
- Detaching/Reattaching the LightHeaded panel
Once the Quest window is closed, the next time it is opened, the temporary misalignment reappears.
The issue is more of an annoyance and not a show stopper for not using either addon.
