Bug Description

On the experimental GTK3 build, if the color palette at the bottom of the screen is small engough (i.e. not enough colors) to not need a scrollbar, the palette resizes from the half-hieght to the full-height whenever the mouse is moved.

Attached is a screencast of the issue.

Conflict with latest Adwaita theme engine for Gnome 3.8?

with short palettes like 'Tango', but only if Inkscape was launched with
to disable the (now gtk-native) overlay scrollbars.

If GTK+'s overlay scrollbars are enabled (default since >= 3.16 IIRC), there's no flickering in the palette (but larger palettes which are scrollable get overlayed with the scrollbar on hover and thus not clickable to assign a color -> separate issue).

Nice research!

I tested using virtual machine produced by inkup - i.e. Lubuntu 14.04 64-git.

Further testing reveal that the jumping only happens when moving mouse over color box' borders, or canvas. Moving over menus, rulers or toolbars leaves the palette inanimate.

I'm not able to reproduce this anymore on r14870.

However, the palette seems to have the old "high hight" temporarily intermittently when switching between palettes or changing their style (width, height ...). Of course not ideal but not a show-stopper anymore, just a minor annoyance.

I don't see why r14870 should have fixed this.

I disabled overlayed scrollbars for swatches in r14781. Overlayed scrollbars were introduced in Gtk 3.16.

What a pain to trace through the layers of objects to find out where to make this fix.

I didn't see the behavior described by this bug either before or after this code check-in. What I did notice is that selecting the "Wrap" option doubles the height of the swatches without doing any wrapping (in a Gtk3 build).

#6 did you try reproduction steps from ?
