Description Eoin O'Neill 2021-06-09 03:11:06 UTC 
SUMMARY
There are some circumstances where the first storyboard entry remains erroneously "empty" when a storyboard-containing file is loaded. This likely has to do with the AsyncRenderer and the code that surrounds it, which could use a cleanup. 

EXPECTED RESULT:
First storyboard entry should render on load, like all other storyboard entries.

REPRODUCE:
Create a storyboard project with a few scenes.
Save the file. Close the file. Close Krita.
Reopen Krita.
Observe the first storyboard entry is missing its visual. Clicking on the storyboard should resolve.

Setting severity to major, since while it appears to be visual only at first glance, it can affect the end result of a storyboard export.
