I observed massive hdd, memory and cpu usage while using thunar with tumbler active. Apparently there is an related upstream bug: https://gitlab.xfce.org/xfce/tumbler/-/issues/73 Gaël Bonithon suggested this has something to do with PDF library poppler, so I remerged tumbler with USE=-pdf and voila! Since this is rather cumbersome to investigate and the fix is not really coming soon, I suppose the default useflag should be -pdf here, perhaps also an ewarn could point here to track the issue. One more thing: I also cleared my ~/.cache/thumbnails in the process, so please check if this workaround is valid prior to implementing. Reproducible: Always
I think the upstream analysis that it would be an "optimisation request" is maybe slightly wrong, in that optimisation isn't really the same as "don't use very unreasonable resources", but w/e. Anyway, yes, the bug isn't new and it's probably worth changing it, although people I assume like their thumbnails :(
