SUMMARY
The title clip editor has an option to display a render of the current preview as background. This background is very low-resolution, making it hard to add precise annotations (see attachment).


STEPS TO REPRODUCE
1. Put a screenshot (1920x1080) into the project (resolution 1920x1080) and add it as a clip
2. Move time cursor to where the screenshot is visible
3. Add a new title clip
4. Enable "Show background"
5. Zoom in (e.g., fit to the screen)

OBSERVED RESULT
The background is shown in a very low resolution; text is almost unreadable.


EXPECTED RESULT
The background (screenshot) is displayed in full resolution.

ADDITIONAL INFORMATION
The resolution of the generated background is not affected by the size of the preview panel (e.g., by double-clicking it to make it full-screen).
The resolution cannot be controlled by changing the window size of the title clip editor.
