Black windows Issue After Prolonged Usage (Still)

I posted this issue before. Since the old post is locked, so I’m creating a new topic about this issue.

And the issue still exists. I have to do a restart when this problem occurs, and this is really annoying.
I guess this might be related to memory.
It seems that the likelihood of this occurrence increases when memory usage is high, whereas it doesn’t appear to happen when memory usage is low. I’m not sure if this is related to the memory management mechanisms. Additionally, this situation tends to occur when a window or a floating window is created, which makes it quite noticeable while typing using an input method. Sometimes, when the window is recreated, it might return to a state where it displays normally.

Did you ever figure out what sr0 was? (I mean I know what it is, but since it seems you clam it not being there…)
There are flaws in your statement at the end of your old thread:

The result from lsblk

sda           8:0    0   1.8T  0 disk 
└─sda1        8:1    0   1.8T  0 part /home/seraphli/Data
sr0          11:0    1  1024M  0 rom  
nvme0n1     259:0    0 238.5G  0 disk

└─nvme0n1p3 259:3    0  16.9G  0 part [SWAP]

fdisk returns nothing related to `sr0
I will update the grub later.

Are you sure you have to reboot? A logout/login does not work?

If you suspect memory, have you ran any memory tests?

Just a wild hunch, is resizable bar available for your gpu and are you then using it?

Are you using nvidia-hybrid?
mhwd -li

A fresh inxi please.

Not to memory management itself, but possibly due to faulty memory, or — and this is often overlooked — memory/CPU/GPU corruption due to electrostatic interference and/or cosmic rays.

From my experience, I can confirm what @seraphil describes.
It happens more likely when the session is > 24h and on higher RAM usage.
On more windows if you keep flatpak apps running too?
I’d like to provide info on this when it happens next time.
What kind of log filter would you suggest to safe info to a text file?

For me this is fixed after a logout/login.

That is an optical device.

Thank you I know that (like I state in the parenthesis you excluded in your quote).
The question was directed specifically to op as you can see I quoted HIM.

I think it’s best to keep them separated until we actually know it is the same. We haven’t heard from op yet.
Best for you is to create you own thread providing as much info as you can.
Read op:s original post (the one he linked to) to find out what to probably provide.

Well, if he reads my post then now he knows. I mean why didn’t you just tell him that if you knew?

Because I actually read the whole original thread, realizing he is not an idiot and probably KNOWS what it is, but missed it in the lsblk.
Please stop.

Save the attitude for someone else buddy.

I don’t know what this problem has to do with sr0. I just run the command and report the result. fdisk does return nothing related to sr0. Is this important to the black windows issue? If not, so be it.

Re-logging into the system might work, but since both re-logging and rebooting require closing all windows, I would choose to update the system and then reboot because they are essentially the same, as both require me to end my work and then reopen windows. I hope to find a way that doesn’t require me to close my windows, or a permanent solution to this problem, rather than resolving it through re-logging, which is not a solution.

I haven’t done memory tests.

There should be error correction mechanisms at the hardware level, right? This doesn’t seem like an issue that could be caused by cosmic rays.

Thank you for providing additional examples to help corroborate the existence of this issue. I’ve searched the forums multiple times but no one has discussed such a problem, so I had to post and ask myself. For me, re-logging also requires closing all windows, which is very inconvenient. May I ask about your hardware specifications? Which graphics card are you using? How much RAM do you have?

I don’t know, but it was mentioned as a reason for one of the errors (or if it was a warning) in your logs in your old thread, and then you stated it wasn’t there, though it clearly was. ^^

I understand that. But it will show if this is related to your desktop or if something worse happens that forces a reboot.

Then do that. Memtest in grub menu I assume?

You should probably run video-hybrid-intel-nvidia-prime instead of video-nvidia

Make sure your system supports prime though, otherwise remove that part.
mhwd -l shows what is available.

Afaik, you can provoke this window-blackening bug by using the Desktop Effect > Slide Back
then waiting for some time or maybe switching between Activities.

Hm, why don’t you use

It will reopen most apps at the state or location they were before (esp. KDE-native apps).

You can find the GPU spec info in my account info.
I’m using a very lo-fi Nvidia card because I bought the PC when the GPU prices were high. I can attach 4 4K screens to it though, in theory. I have 2x 32GiB DIMM DDR4 @ Synchronous 2667 MHz.

I still don’t understand. I didn’t put any output of fdisk -l, so where do you see sr0 in the output of fdisk?

Reopening windows is not what I want. For example, when I run a code on this PC, I have to finish or stop the process in order to do a restart.

My graphic card is not very well, and I attached 2 4K screens. The monitors sometimes lose signal when turned off. So I have to keep the screen on all the time. Though this is another problem.

It seems video-hybrid-intel-nvidia-prime is not a valid option. This computer is an old antique; it might not support that.

I will do it later and update the result. I currently have the machine on in case I need some information now, because after restarting, there’s no telling when this issue might reoccur.

I just found out that this time the problem seems to have resolved itself automatically. I haven’t restarted the computer, but it appears the black windows are not showing up anymore. Currently, my RAM usage is at 49.4%. I’ve encountered an automatic recovery once before, which I suspected was due to memory usage because at that time I only had 16GB of RAM. So I closed all windows to free up memory, and afterwards, the problem disappeared without a restart.
And I just noticed one wine application I used stopped responding. I don’t know if this is related to this issue. I do use that application a lot.

I just remembered that I encountered this issue before when I was using 16GB of RAM. Now I am using newly purchased RAM sticks, the original memory is no longer in use, and I’ve upgraded to 64GB of RAM, yet the same issue has occurred. Given this situation, I think I probably don’t need to run a memtest.

And you bought memory supported by your motherboard? Made sure the timings got set correctly in bios?

Other than that I don’t have much more to give.
Oh, and maybe not:


That might have something to do with it.
