Bug ID: 527246
Summary: Spectacle crashes on UnionStyle::drawControl
(backtrace available)
Classification: Applications
Product: Spectacle
Version First unspecified
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: General
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
DESCRIPTION
Discovered while setting the font size of the texts of my last two bug reports.
Had to use Photos to edit those.
Having Union app style set, Spectacle crashes while manipulating some of its UI
elements such as the color picker or the font size/style picker. Could not
reproduce this reliably.
STEPS TO REPRODUCE
Could not reproduce reliably. Poking around UI elements such as the font or
color picker was enough to trigger this twice.
OBSERVED RESULT
Spectacle crashes on UnionStyle::drawControl. Backtrace is shown below.
EXPECTED RESULT
Spectacle should not crash just by using the Union engine.
