Description Michael 2023-01-09 12:25:14 UTC
since last upgrade (a week ago) from plasma 5.26 to 5.26.5, I don't see larger thumbnails, just placeholder appear
in my case it are .SRW raw photos from Samsung camera, the files are TIFF, not embedded JPGs as Sony Raws 

larger thumbs mean larger than gwenview's standard size thumbs in folder view

I can zoom out thumbs until the smaller ones appear(80pix wide), zooming in they disapppear

in gwenview I can zoom in without any problem

apt list dolphin
dolphin/jammy, now 4:22.12.0-0xneon+22.04+jammy+release+build14 amd64 [installed]
no missings deps or broken pkgs, everything else works fine

Plasma v 5.26.5

same happens with Kde Neon

Maybe a KImageFormats regression with a frameworks update that happened around the same time? Starting there.

I don't really understand the text of the bug report.

Bug i guess you're saying you have files that used to be thumbnailed in dolphin and now are not?

If so, we're going to need one file like that.

adding more info, .xcf files are also not being thumbnailed any more, application typ and filetypes are correctly created by GIMP install

BTW, I suggest creating JPG thumbnails and not PNG as it is now, JPGs thumbnails are notable faster to create 

I have emptied the ~/.cache/thumbnails folder, nothing changed, just JPGs are reated, small thumbnails are created by gwenview when in folder view (as reported initially)

adding attachment a .SRW and .XCF

kio-extras/dolphin/gwenview/kdegraphics-thumbnailers is all 22.12.1-1
