Desktop icons losing text after suspend

[JohnEverest]

After return from suspend the desktop icons have lost text description. There is a white rectangle on a black background. Recovery by logout/login or restart sddm. Changing desktop theme does not affect the problem.

System:- Kubuntu 16.10, KDE Plasma 5.7.5 , KDE Frameworks 5.26.0,
         Qt Version 5.6.1
         Kernel Version 4.8.0-22-generic
         Graphics card Nvidia GTX 750/PCIe/SSe2

I also have Kubuntu 16.10 64bit running on a Dell Latitude E6400 laptop. This does NOT show this bug.

[Balazs Nemes (bazsix)]

I'm using Kubuntu 16.10 on an Asus K501LX laptop and experiencing the same. It has Core i7-5500U and nVidia GTX950 with nvidia proprietary drivers.

[Balazs Nemes (bazsix)]

For me the bug takes effect only when the nvidia GPU is active. If the rendering is performed by the Intel integrated GPU the icons are rendered correctly after suspend. But when nvidia GPU is choosen then the text of the desktop icons seems to be some random memory garbage after a suspend.

[JohnEverest (john-everest)]

Currently testing with Kubuntu 17.04 daily build 21/01/2017. No change

[Damien (damien.kde)]

Also affected, using Kubuntu 16.04 with NVIDIA driver 375.39.

[JohnEverest (john-everest)]

Still a problem in Kubuntu 17.04 release (Updates to 13/05/2017)
Resizing a desktop icon restores text description.

[Simon Quigley (tsimonq2)]

Thank you for taking the time to report this bug and helping to make Kubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Kubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Kubuntu version. If you test it and it is still an issue, kindly upload the updated logs by running only once:
apport-collect 1634389

and any other logs that are relevant for this particular issue.

[JohnEverest (john-everest)]

Now running Kubuntu 18.04 problem still exists. However it does NOT occur with the default Nouveau video driver but returns when the recommended 4.6.0 NVIDIA 390.48 driver is installed.
Still need to restore icons by changing icon size to something else and then back again.

[jay marm (jay-marm)]

I'm running a clean install of Kubuntu 18 with the latest Nvidia drivers and am having the same issue: text on icons are a block of coloured static with black borders after suspect/resume.

I haven't found a way to refresh them other than to reboot.

[Scott Deagan (scott-deagan)]

This seems to be a long standing issue that has yet to be resolved. It seems to only happen with the Nvidia proprietary driver (I don't experience the issue when I'm using the Intel iGPU).

In response to #10: you dno't have to reboot. You can run:

killall plasmashell && kstart plasmashell

from the terminal.

[JohnEverest (john-everest)]

I can reset the icons just by resizing the icons from the desktop. Right click > icons > icon size.

I am currently testing Kubuntu 18.10 daily. About one week ago the problem appeared to have been fixed but with the latest updated it has returned.

[Launchpad Janitor (janitor)]

[Expired for Kubuntu PPA because there has been no activity for 60 days.]

[Lucian Ator (luator)]

Still an issue on Kubuntu 19.04. I am using the Nvidia driver.

[Christoph Haas (chaas)]

Same on 20.04 by the way.
