Description Nicolas Fella 2022-05-28 14:12:51 UTC

STEPS TO REPRODUCE
1. Go to Edit > Resize image
2. Enter a large width, e.g. 100000px

OBSERVED RESULT
Gweview freezes/hangs

EXPECTED RESULT
Gwenview doesn't hang

SOFTWARE/OS VERSIONS
Gwenview: master (72e38e5a5831728d37b7548ab430171e73857cbd)
KDE Plasma Version: master
KDE Frameworks Version: master
Qt Version: 5.15.4-kde

ADDITIONAL INFORMATION

It seems to hang in calculateEstimatedImageSize() doing lots of IO.
Moving the image size estimation to another thread might help

Still reproducable.
