Description rittels 2019-09-09 19:37:47 UTC

SUMMARY
When using the line tool with the "Show Preview" the preview is delayed by a whole second and shown only when pausing.
If "Show Guideline" is checked, the guideline will appear instantly and update live, otherwise nothing whatsoever is shown until you finish the line or pause for a second.

STEPS TO REPRODUCE
1. Activate line tool
2. Make sure "Show Preview" is checked
3. Draw a line

OBSERVED RESULT
Delayed preview, only appears if pausing the line for a whole second.

EXPECTED RESULT
Live, instantaneous preview (as if i were drawing on a ruler).

SOFTWARE/OS VERSIONS
Windows: 10 (x86_64)
