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).
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?
