Subject: bug#13123: 24.2; Resizing frame partly resets background color
Date: Sat, 08 Dec 2012 10:57:02 +0100

[Message part 1 (text/plain, inline)]

Hi there,

resizing the Emacs frame causes the background color that has been set
via a theme or directly via M-x set-background-color to be reset to a
default value, except for the parts with (visible or invisible) text on
it. Steps to reproduce:

1. Start Emacs
2. M-x set-background-color and choose any background colour you like
3. Resize the frame

The effect can be recovered by again doing M-x set-background-color or
reloading the current theme (until the next resize). See the attached
screenshots for a demonstration (order in which they were taken is
preresize - postresize - postreset).

This is 100% reproducible on my two machines here running 64-bit Arch
Linux with i3 as the window manager in an otherwise mostly XFCE
environment (i3 is a tiling window manager and as such resizes windows
all the time). Emacs is in both cases the stock emacs from the Arch
Linux repositories. The GTK theme in use is the Xfce/gtk-3.0 theme.

Greetings,
Marvin
