Description Aron Heinecke 2020-01-11 18:28:15 UTC 
SUMMARY
Akonadi background processes use GPU memory from start to end of akonadi.

STEPS TO REPRODUCE
1. Open KMail
2. Close Kmail
3. run nvidia-smi

OBSERVED RESULT
nvidia-smi reports the following

+-----------------------------------------------------------------------------+

EXPECTED RESULT
No akonadi_* processes that use GPU memory while running in background.

Although I can understand that some processes can be speed up by using the GPU I can't see why there are so many processes from akonadi or why archivemail or mailfilter need it at all.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KUbuntu 18.04.3
(available in About System)
KDE Plasma Version: 5.12.9
KDE Frameworks Version: 5.44.0
Qt Version: 5.9.5

ADDITIONAL INFORMATION
Running akonadictl stop obviously removes all those akonadi_* processes from the memory reporting.
