SUMMARY

Gwenwiew may take all and more that it ram if it opened in directory wich hawe too much pictures (gwenview start makeing previevs of all pictures in directory untill all pictures will be processed)

STEPS TO REPRODUCE
1. Create a directory with many pictures
2. Open any picture in it with Gwenview
3. Look how you ram will be whiped with Gwenview while it creates previevs for all pictures

OBSERVED RESULT

Nearly whole system start lagging and working slow since it had to move some gvenwiew ram in swap

EXPECTED RESULT

Gwenview will load only some pictures from directory and will load/process extra as i will change inside gwenviver

SOFTWARE/OS VERSIONS
Linux/KDE Plasma:  5.4.105-1-MANJARO  / Plasma 5.21.3 


ADDITIONAL INFORMATION

I not a coder, but something is telling me that you will had to do some ram usage limither wich will halt extra images processing untill user will scroll near to end of processed pictures

Relevant information from IRC:
”no realy, i hawe like 40+ thousands pictures”

It might be useful to also say how much RAM your system has.

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Gwenview 25.08.0 (the latest released version)?
