Loki wingpanel problem

Hi there!

I've got a question concerning the wingpanel (that's the bar at the top, right?).

Every 20-30 s or so, it disappears for a short time, all windows move up to fill the screen, then it reappears and everything shifts down again.

Does anyone else have that problem or even better know a solution?

Best regards,
Fo

 

Hi,

I've got a similar problem, perhaps the same origin. My wingmal / application panel only shows up shortly after pressing Super-Space (with Super = Windows key), then disappearing again. Together with this, the clock and the icons in the top right corner appear and disappear.

I read the messages here
http://elementaryos.stackexchange.com/questions/7680/wingpanel-not-responding-loki
http://elementaryos.stackexchange.com/questions/1458/wingpanel-crashing-after-update

and deinstalled the said critical packages with
sudo apt-get remove indicator-synapse
sudo apt-get remove wingpanel-indicator-power

with no effect.

dmesg shows the following signature after pressing Super-Space:

I don't get information from this, but is there an experienced hacker who knows where to tweak by this...?
Thanks for any hints, as this is an annoying bug/feature...

 

the trap error is showing sigint 3 == simular to ctrl+c to interrupt a program.
But: there are simular problems with Gnome 3.20 and some versions of the nvidia drivers.
IF you have an Nvidia card, and you are using the prop. nvidia drivers, try if you have the same problem with the nouveau driver

 

Thanks for the quick reply. Yes, I have a nvidia card. To be honest, I was that upset about that bug that I installed Linux Mint meanwhile. I will give elementary a second chance in some time again.

 

Hi, same problem but I have AMD APU, no Nvidia. I tried uninstall synapse and power without success. Any idea?
