Image previews (with Ueberzugpp) seems to be bugged in Wayland

[hakobi0]

In a Wayland desktop, with Ueberzugpp compiled from source with Wayland enabled,
it doesn't seem to respect lf borders
I'm unsure if this is an Ueberzugpp problem or a problem with the script.

lf version r39
terminal alacritty

Any idea of what can be done here?

Have you tried inspecting the actual x,y coordinates sent to Ueberzugpp? You can modify the previewer script (i.e. the draw function from the wiki example) to log the values to a file. You can also try putting in hardcoded values for the location/size and see what happens. If the values are calculated correctly but the image is still displayed in the wrong location then it is an issue with Ueberzugpp.

Interesting, I have modified the script to create a log file. It seems to be a problem with the Wayland mode of ueberzugpp, the chafa method doesn't have this problem, neither does the kitty mode, its just something weird from the wayland method.

Hi, I know this is not a solution you expect, but foot supports sixel and is about as fast as alacritty in ui even without gpu acceleration, and takes half the time to open.

# from my image preview script
WIDTH="$2"
HEIGHT="$3"
chafa --polite on --dither fs --color-space din99d -f sixel \
    -s "${WIDTH}x${HEIGHT}" --animate false -- "$1" && exit 1

It has no problems with drawbox.
