Hi all!
I have a monitor with 2560x1440 pixel. When I open an image with kuickshow in fullscreen
with scale to fit the creen then the image is not always centered and shows artefacts in
the supposed-to-black regions of the screen (see screenshot).
Anybody seen this happen before?

I have not seen it in kuickshow (which I use every day), but I have seen
something like it in some other applications.
When I create my own background for the TDE login page (on first boot), I must
set it for "scale and crop"; otherwise, I get this effect. I think it is, or
has something to do with, tiling. (This is found in TCC / Login Manager /
Background - English version, but you probably know what I mean.)
Also I have encountered it in an altogether different place, but it is a
similar situation. I have a small blog, which has virtually no readers; I use
it mostly to post things for my own future reference. But I created a
background for it, and despite trying to tweak it with css and using every
html trick that I know, I get this same tiling effect.
In both cases, it looks a lot like what I see in your image. Not that this
answers your question, but it may help you to find some kind of solution. And
I would be interested in solving my own problem with tiling of images, if it
can be applied to my own cases.

I don't have a monitor that big but I have three monitors forming a single
4960x1200 desktop so I used kuickshow to scale a 4032x6048 image down to
fit the desktop and then up to several sizes peaking at 9112x13668. I did
not observe any artifacts.
During this experiment virtual memory used by the kuickshow process was
fairly stable but video RAM increased with image size up to about 500MB.
Fortunately I have 4GB of video RAM.
Is it possible that you ran out of video RAM?

amd64 here but still on Buster nvidia proprietary 418.181.07-1
(switching shortly to 418.197.02-1).
I looked into upgrading my *nvidia* packages to Testing to
investigate this but it would be too disruptive at this time.
