Comment 11 for bug 1387533

I noticed that the maximize button remains when a window is snapped to a corner.

Here is a repost from one I just did on launchpad:

I upgraded to Xfce 4.12 via the PPA and did some testing with as many installed programs could find that can be resized.

Most of them did not have the issue at all. It was intermittent, so who knows...

I believe Blender had the issue the first time I tested it when I snapped it to a side but it did not occur again with the same program instance. I'm not sure if it was just a one-time graphical glitch.

However, Chromium 43.0.2357.130 Ubuntu 14.04 (64-bit) consistently has this issue when snapping to a left or right side edge, it will show the maximize button and left clicking it has no effect while snapped left or right. Closing and relaunching does not fix it for Chromium.

"xfwm4 -V" gives me:
