Black shadow outline remains after network connection tooltip

[Chapu]

I've experienced this issue in all of the MATE installations I've done so far (all of them with Linux Mint), on different architectures, hardware profiles, and MATE versions (from 1.2 onwards).

Simply put, when I hover the pointer over the network connection icon at the bottom right of the screen, a small pop-up appears with some details about the current active connection. This pop-up is standard behaviour on all of the plugins in the desktop bar, as far as I can tell. But the network connection plugin has an unexpected behaviour, in that the shadow that accompanies the little pop-up remains in the screen after the pop-up is gone. See the following screencaps for an example:

pop-up message with outline present: http://s10.postimage.org/9c8z6f8uh/Screenshot4.png
pop-up message gone, the outline remains: http://postimage.org/image/aryzv3gff/

I'm pretty ure it's a Marco thing, because I briefly tried Compiz and this didn't happen.

I have same issue. Confirmed

I can confirm the issue too (with compositing enabled).

@ketheriel That's no joke! That's the actual name of my home's wifi, for the delight of the neighbours. I have a... let's say peculiar sense of humour :-D

I have seen the shadow glitch also in a quite a lot applications (glade, yelp etc.) when a tooltip has been displayed

Seems like this happens with all pop-ups from GTK3 applications. I also tried the GTK3 versions of brasero and gnome-disks and got the same results with their pop-ups.

I remember seeing this but have not for some time now. What gfx card/drivers do you use? I am now on intel hd4k.

Hmm, I think I have a "Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)". I'm not much into hardware but as far as I understand, it's some pretty cheapo low-end stuff, not the expensive "gamer" stuff. There seem to be open-source drivers done by Intel for that one. It looks like my driver for X Windows is called /usr/lib/xorg/modules/drivers/intel_drv.so.
