XFCE panel (Deskbar mode) notification area glitch

Hi,

I'm experiencing a glitch for some icons in notification area in Manjaro (stable, x64, XFCE 4.11).
Sometimes icons in Deskbar's notification area have black stripes at the bottom and right (Deskbar_glitch.png).
It happens on system start or when some icon disappears.
Octopi ( http://octopiproject.wordpress.com/ ) icon is most often affected, but some others look like this too sometimes (Skype icon, for example).

I've experienced this with Maximum icon size (px) = 24 and Maximum icon size (px) = 25.
I have tried changing Maximum icon size in Notification area properties, when glitch was visible. After changing size things go back to normal (Deskbar_normal.png). After this - no matter what Maximum icon size I set - black stripes don't appear until reboot.

It's also worth to note that octopi-notifier, which is most often affected by the glitch, doesn't always appear in notification area on startup, but this is most probably strictly Octopi issue.

Things, I have tried to resolve the issue (based on Manjaro forum users' suggestions and my own ideas):
- clearing sessions;
- changing state of "Show frame" checkbox in notification area properties;
- generating  cache file for my icon theme (Faenza);
- switching theme and icon theme, while glitch is present, doesn't affect it (it remains visible no matter how many times I change one of these themes);
- as Octopi has only 32x32 icons in /usr/share/icons/octopi*.png and in /usr/share/icons/gnome/32x32/apps/octopi.png, I've made links for Octopi icons from /usr/share/icons/ in /usr/share/icons/Faenza/apps/32/ and updated icon cache for Faenza. This attempt did not fix neither Octopi missing icon issue, nor black stripes glitch, because after 2 reboots I had missing icon once and glitch the second time.

None of these actions helped, so I'm asking about this here.

Any ideas?
Thanks.

Re: XFCE panel (Deskbar mode) notification area glitch

I've found that this glitch happens only with Qt apps' icons.
I have 3 such icons: goldendict, octopi, skype - glitch happens for all of them sometimes.
I have both qt5 and qt4 installed, at least goldendict is using qt4. I suppose that octopi and skype are using qt4 too.
Does anyone else experience this kind of glitch?

This bug was somehow fixed with the last Manjaro update-pack: 10 boots and no glitch.
Bug with octopi icon not always appearing in notification area was solved with this update-pack too.

The issue is back along with newest XFCE 4.11 packages

Workaround: setting maximum icon size (px) = 22 in notification area properties eliminates the glitch.
