I see dead pixels

I am having similar hallucinations as this user: https://ubuntu-mate.community/t/ugly-black-squares-on-window-title-bar-in-pluma/23641.
On Trisquel 11, it first happened with Abrowser, until I noticed that it happens with any application when the window is resized in such a way that the title cannot be fully displayed. The animation in that thread says it all. My experience is also similar in the sense that it happens with any theme, and any compositor settings (no compositor, any of the various suggestions in MATE Tweak, and either with or without checking "Software composition" in mate-window-properties).
It is so freaky I dare not post it in the main section of this forum yet, for fear of putting off new users, but it should probably be reported somewhere, at some point. Attached a typical example with mpv. What do you think? Is it a good idea to call the undead pixels? Or is this another tearing problem?

I don't have this problem.
As a wild wild guess, you are not using Intel integrated graphics, are you?
I am, at least on the machine where these archeological artifacts appear, and so is the other hallucinator. I may never have noticed them, if not for a mouse jitter that sent Abrowser to widget size. I will test on another machine, one with a non-Intel GPU available. It will be a good occasion to put that otherwise useless card to work.
I also see smaller white rectangles inside Abrowser, but I may not reveal all at once.
I have Intel integrated graphics and I don't get those little black boxes in the title bar. I'm still using the original ugly gray Mate theme though, not something with nice dark colors.
I am a translator!
I think the T400 uses the integrated graphics. I did not notice that with MATE. However, I am using dwm now, so no title bars (and I don't miss them).
But you are missing the fancy artifacts.
> I think the T400 uses the integrated graphics
Specs for the T400 seem to be hybrid graphics:
* Intel Graphics Media Accelerator 4500MHD
* ATI Mobility Radeon HD 3470 256MB with Switchable Graphics
So you may in fact be using the ATI dedicated GPU. What does your MATE system monitor say about your system graphics?
> the original ugly gray Mate theme
This one is not available on my system.
UPDATE: you are using DWM. You go out.
Right now I'm using XFCE with a nice dark theme, and no black boxes in the title bars.
Maybe your computer just doesn't like you?
They all seem to hold a grudge against a certain Marco. Is that you?
No, I'm a very uncertain Marco.
That explains everything.
Can we now consider this thread "solved"? Or shall we bury the truth in the bowels of this comment thread?
I'm sure you're referring to the realtime kernel thread, but I'm sure you were aware I was only trying to determine "could" it be installed and run, which I did after a few things got ironed out.
You seemed to be digging into the alternative question "should" it be installed, and seemed to find it to be a vulnerable kernel, which I don't disagree with.
Or was there more distinction to what you were saying that I failed to grasp? I had no intention of causing you any angst.
No, I thought you may have been appointed Special Thread Police Brigadier, and it is basic survival wisdom never to stand in the way of a Special Thread Police Brigadier in duty, especially for resident trolls. They are not immune to bouts of angst whenever such an encounter happens.
Since you are asking, I only had one remaining question about what/where in the repo is that 5.15.whatnot-realtime kernel that both you and the OP seemed to have been playing around with. I wanted to play around too, but could not find it in the repo. Not that I need it, though, and not that the Linux-libre 6.XX-rt version is not fit for its purpose. I am quite fine leaving that story to rot in the bowels or dry in the sun, and trolling you about it from time to time.
I hope you did not experience any angst, or sleeping problems, or bowel discomfort, or whatever, because of a thread, but I realize now that something did bother you. My aim was to enquire and learn a bit more about this "low-latency" vs. "-realtime" vs. "-rt" vs. "-tomorrow-will-be-too-late" vs. "-take-it-easy" vs. "-hardly-really-slow-snail" kernels. These kernels are beginning to be a huge mess, not to mention "hwe" and "hardened" versions, etc. It is not human to have to keep track of so many kernels. I am glad to be a Hutt.
I believe HyperbolaBSD's HyperBK will be much tidier. The roadmap currently says:
"Test HyperbolaBSD pre-alpha version running on QEMU (without Xenocara) → IN PROGRESS". Wooh!
I only had one remaining question about what/where in the repo is that 5.15.whatnot-realtime kernel that both you and the OP seemed to have been playing around with.
I found it in Trisquel 11's repository at the time https://trisquel.info/forum/how-install-realtime-kernel-trisquel#comment-173778 was published. Since then, the package has apparently been removed.
Oh! An evil conspiracy against real-time kernels has been unearthed.
Thanks, this totally answers my question.
>""-tomorrow-will-be-too-late" vs. "-take-it-easy" vs. "-hardly-really-slow-snail" kernels"
Are these in the Trisquel repo? I could use them alongside my Tesla Self-driving kernel.
>"I hope you did not experience any angst, or sleeping problems, or bowel discomfort"
Your concerns about my wellbeing are very comprehensive. I do have one ingrown toenail that I'm blaming on your comments. So there's that.
>""Test HyperbolaBSD pre-alpha version running on QEMU ... → IN PROGRESS". Wooh!"
Wow! MoOOoo!!
>" ... without Xenocara"
Well, I sure hope Xenocara gets a "with" instead of a "without" soon enough. Xenocara display server is one of the primary reasons to use Hyperbola. It's originally an OpenBSD project and it has big security advantages over Xorg.
Really? I thought Xenocara was Xena's cousin once removed.
I did put that otherwise useless card to work, and guess what? It works. No fancy boxes around window titles when they get truncated.
The graphics are elegantly called "llvmpipe" while the dedicated GPU is in use. I may keep it at hand after all.
I am also getting the fancy boxes with the Intel integrated graphics on the same machine.
Issue reported.
