Description Netterfield 2006-07-31 23:36:26 UTC
Version:           1.3.0_devel (using KDE 3.5.3, Kubuntu Package 4:3.5.3-0ubuntu0.2 dapper)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.15-26-386

Create a plot
in the plot, make an image with fixed aspect

Repeatedly enlarge and shrink the window (quickly).  After a while, the aspect will drift (either wider or narrower).  Edit/apply the image will reset the fixed aspect to the correct thing.
Comment 1 Duncan Hanson 2006-08-01 18:30:08 UTC
sounds like resize is being called when it should be parentResize.

SVN commit 568580 by dhanson:

CCBUG:131620 fixed. the problem was the myOldGeom did not necessarily have the proper aspect ratio, particularly if _geom.setSize(_geom.size().expandedTo(_minimumSize)); had been called.
