Problem with Icons on Desktop after resuming a suspended system

My PC:
- Motherboard: Asus Crosshair VI Hero
- Graphic card: NVidia Geforce GTX 1070
- Processor: AMD Ryzen 7 1700
- RAM: 32 GB

I previously resolved these problems:
- Incorrect drivers for NVidia according to NVidia wiki (https://wiki.archlinux.org/index.php/NVIDIA)
- Screen tearing, according to this page: https://www.gamingonlinux.com/articles/ … 892/page=5

Current problem:
- When resuming my suspended OS, background color for captions of icons on my desktop don't get properly showed, it seems to be a problem with transparency. I attach an image:

Request:
- How can I resolve this problem?

Thanks in advance.

Re: Problem with Icons on Desktop after resuming a suspended system

It seems that you're using Plasma desktop. Are you using proprietary NVIDIA drivers?

If so, this is a known Qt issue with proprietary NVIDIA drivers:

Yes, I'm using Plasma, but I'm using open drivers for Nvidia (recommended by wiki)

Re: Problem with Icons on Desktop after resuming a suspended system

If you followed the Nvidia article you are using the proprietary drivers, it's also quite unlikely for nouveau to have good support for that graphics chip.

Re: Problem with Icons on Desktop after resuming a suspended system

I'm not sure if this also applies to the open source drivers.

On the Qt bug report there is a proposed patch to fix it. You can try to build qt5-base with this patch and see if this solves your issue. Of course you must know what you're doing if you're willing to take this step.

It worked for me with proprietary drivers way back when I tested the patch.

Dear dbermond, which would be the steps to use this patch? If it does not work, which would be the steps to undone any changes done for this patch? Thanks in advance.

Note: the patch is located in this page: https://bugs.kde.org/show_bug.cgi?id=364766 , right?

Re: Problem with Icons on Desktop after resuming a suspended system

Look at https://wiki.archlinux.org/index.php/Arch_Build_System and https://wiki.archlinux.org/index.php/Patching_packages for guidance on how to get the package source and applying a patch. This is easily revertable by simply installing the repository version again should the patch not bring the desired effect.

Already answered by @V1del.

Yes, the patch is at the KDE bug tracker (the original bug report).

Direct link to the patch:
https://bugsfiles.kde.org/attachment.cgi?id=107684

Note that you're not supposed to ask on the KDE bug tracker about how to use a patch, specially if you say to be an Arch Linux user

Re: Problem with Icons on Desktop after resuming a suspended system

First off, thanks dbermond and V1del for your answers. Sincerely I've read the pages mentioned by V1del and I feel I'm reading a Chinese article, I don't know how to start 'cause I'm a newbie yet
That's the reason why I'm requesting specific steps, please.

Note: the file downloaded is "0001-NV_RESET.patch"

Re: Problem with Icons on Desktop after resuming a suspended system

I've read once again the section "Applying patches" from https://wiki.archlinux.org/index.php/Patching_packages, but I don't get it, so from the directory ~/Download, where this patch is located, I tried to run the following sentence by getting this output:

$ patch -p1 -i 0001-NV_RESET.patch
can't find file to patch at input line 15
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:

Re: Problem with Icons on Desktop after resuming a suspended system

It seems that you're blindingly applying the patch in nowhere at the shell prompt. This is not the way to go.

First of all, keep in mind that you'll need to build a (patched) package that can be installed by pacman. So you'll have to modify a PKGBUILD file for this.

After gathering the Arch Linux sources for building qt5-base, you'll need to modify the PKGBUILD file in order to apply the patch, and then build the package.

The Wiki articles pointed by @V1del will guide you through this. But if you don't have any knowledge about creating and modifying packages it will be a bit difficult, and you'll need to read more Wiki articles, like these ones:

https://wiki.archlinux.org/index.php/Creating_packages
https://wiki.archlinux.org/index.php/PKGBUILD

Note that there is also a chance that the patch will fail to be applied, because it was designed at a previous Qt verion (5.9). In this case you'll have to make some adjustments in the patch and this would require some programming skills.

Re: Problem with Icons on Desktop after resuming a suspended system

Thanks dbermond, I can see the complexity of this task and the uncertainty of this patch. For the moment, this "error" with icons is not that bad, so I can live with it.

Good choice. Just wait for the upstream fix. Unfortunately it may take a while.
