Some icons and text randomly become invisible after waking up from sleep (Ubuntu GNOME)
Icons and application indicators in the dropdown settings sometimes disappear.
This happens after waking up from sleep, and can be fixed until waking up from sleep again by pressing Alt+F2 and typing r.
Does anyone know how to permanently fix this?

This seems to be a bug in the graphics driver, so it should be reported once we know what triggers it (hardware, driver).
That said, there have been lots of similar bugs and people came up with workarounds there which you can also try for this one.
In case you have an Intel graphics card, here are some workarounds to try:
Reserve memory for the graphics adapter. In the Intel graphics driver (
i915), pixmap caching issues like yours are often connected to the fact that the graphic card's shared memory is dynamically allocated from system memory, so also takes part in swapping, read-back from disk etc. where things can go wrong. So one workaround is to use thememboot parameter to leave enough RAM unallocated by Linux that is then used exclusively by the graphics card. See the detailed instructions. But note that on x86 systems (32 and 64 bit), thememparameter is actually a maximum address [source], so has to be set higher (determined by experiment) than the amount of RAM to leave for Linux.Disable swap. Again for Intel graphics, not including the shared graphics memory in swapping can be a workaround. Especially promising if the problem mostly does not appear after a fresh reboot, only after prolonged and memory-intensive work. So if you have enough RAM, you can just disable swapping completely by adding
swapoff -ato/etc/rc.local[source].Try UXA acceleration. It's an option for the X config file, details here.
Try framebuffer BLIT mode. Again for Intel graphics, you can try
sudo echo COGL_ATLAS_DEFAULT_BLIT_MODE=framebuffer >> /etc/environmentand then reboot. [source]Try to reset Compiz to default settings. Reported here (but quite some time ago) to have helped with similar issues. Or while we're at it, try a non-compositing desktop manager instead of Compiz.

Restart the GNOME shell without interfering with any already opened windows using the following command and the missing Panel icons will reappear.
setsid gnome-shell --replace
Press Enter again before closing the terminal.

The suggested solution is to upgrade the kernel from 4.4 to 4.8:
sudo apt install linux-generic-hwe-16.04
I did that today, but since I only had the problem a few times in the last months, I can't testify to the effectiveness of this solution. However, others in the bug comments confirm that it solved the problem for them.
