Garbled screen and system crashes

acgray94 · 3 April 2025 22:02

In the past month or so, I’ve started experiencing a lot of screen glitching (some examples below). The screen glitches are not limited to any specific program, and I believe they’re an OS/driver related problem rather than an issue with my laptop’s display because the glitches stay locked with the content of webpages/PDFs etc when I scroll. I can’t be 100% sure but connecting and disconnecting my laptop to an external display does seem to make the glitching more frequent.

At the same time, I’ve started experiencing worryingly frequent system crashes (up to 2-3 times a day). Sometimes it just seems to be KDE that crashes (screen goes black and then I’m back at the login screen starting a new desktop session), and other times my machines fully reboots. I can’t spot any particular pattern in what causes the crashes, sometime they happen exactly when I launch a program or click a link, sometimes they happen out of the blue. I’ve tried looking through the systemd journal with journalctl but cannot see anything incriminating happening before the crashes.

The fact the screen glitching and crashes started happening around the same time makes me think there is a common cause, hence posting to the KDE category and not specifically the graphics one. Any advice on how to start investigating this would be much appreciated.

Some system information:

Lenovo thinkpad P14s
AMD Ryzen 7 7840U CPU
AMD 780M integrated graphics
KDE Plasma 6.3.3
KDE Frameworks 6.12.0
Qt 6.8.2
Linux 6.6.84-1 kernel

Basic system information such as that provided by *-fetch type programs or desktop environment system summary pages might be fine for someone wishing to buy your computer but for Support purposes it’s best to ask your system directly using the inxi command.

Please provide system information as described (below).

Please ensure all code or command output is displayed as preformatted text (see link below).

Welcome to the Manjaro community

As a new or infrequent forum user, please take some time to familiarise yourself with Forum requirements, and the many ways to use the forum to your benefit:

Update Announcements

The Update Announcements contain important information and a Known Issues and Solutions section that should generally be checked before posting a request for support.

System Information

Output of this command (formatted according to forum requirements) may be useful for those wishing to help:

inxi --filter --verbosity=8

or the short form:

inxi -zv8

Be prepared to provide more information and outputs from other commands whenever asked. It’s equally important to provide as much actionable information as possible in your first post, rather than simply indicating there is a problem.

Hey scotty, thanks for the info. The CPU/GPU info on my profile is for my desktop machine, whereas this issue is with my laptop, hence the inconsistency.

Is there any particular reason why you are running Plasma on x11? You don’t have an Nvidia GPU (they seem to be the main/only cause of issues with Plasma on Wayland), and Plasma Wayland works very well with AMD GPUs.

You can switch to a Plasma Wayland session by selecting it at the bottom of your SDDM login screen.

If you use autologin to skip entering your password, then you can change session types by opening System Settings → Colors & Themes → Login Screen (SDDM) → Behavior.

No, don’t think I ever explicitly chose to use x11, I guess it’s just the default. Will give Wayland a go and mark this as the solution if I don’t run into any issues after a few days. Thanks!

acgray94 · 5 April 2025 21:54

Unfortunately switching to wayland hasn’t fixed the glitches

BG405 · 6 April 2025 04:12

It does, unfortunately, seem like it could be a hardware issue, at least to me. I’ve seen similar with ailing graphics cards.

One test would be to boot and run from a Live USB for a while and see if the problem occurs there.

12 days later, and a new entry to the thread - but still no answer to this excellent suggestion.

Moderator Note:

Topic title changed for consistency with similar issues in the last few days – using “garbled” as a keyword.

A post was merged into an existing topic: Garbled screen in some applications

acgray94 · 26 April 2025 15:21

Sorry, I haven’t had the time to test a live USB boot yet, I’m in the middle of writing my PhD dissertation so have put almost everything else to the side for a while.

I’m not sure if the issue has improved in the last 3 weeks, but I have noticed that it only seems to start after I close (enter sleep mode) and re-open my laptop. So I have basically avoided the issue by just not closing my laptop. Not a long term solution I know, but maybe a useful data point. Also, as somebody else in the topic said, the issue does seem to flare up particularly badly with firefox.

varikonniemi · 26 April 2025 15:31

it sounds like a low level graphical memory corruption issue since it happens on both X and W, after a sleep cycle and when using FF (meaning probably HW video acceleration)

You could test the oldest and newest kernel available to see if that makes a difference, as that is where the video driver lives.

acgray94 · 26 April 2025 22:10

Thanks! I updated my kernel to 6.12 LTS (linux612) and it seems to have fixed the issue. No screen garbling/glitching after several sleep and wake cycles.
