htop screenshot of RAM usage

SUMMARY

Over long periods (current uptime about 11days) where i only suspend and wake up the PC I noticed a substantial RAM increase. (~10gb so far)  This happened for the 2nd time by now. 

Sadly i don't know what exactly caused the problem or how to reliably reproduce it. Maybe someone could tell me what logs or other information might help to solve that, for now i plan to just keep it running until I'm out of RAM.

Sorry I have no clue what was happening.

The QML garbage collector may decide to free up memory when the free memory is low, so it may never run out of memory, but need more test data.

Sorry it took us so long to get to this. I can't reproduce it in current git master, which will shortly become Plasma 6.3. Are you still able to reproduce the issue in Plasma 6.2.5 or later? Thanks!

At some point it just stopped to happen, so sadly cant help with that anymore. Sadly cant even tell if it stopped before or after i switched to an AMD GPU.
