Description Lane Wiscombe 2014-10-12 06:00:59 UTC

I am on a multiple monitor setup with kubuntu plasma5, seems like the shell would get high memory usage alot over 500 MB and my mouse will start stuttering for a while then it will stop... I am on a AMD FX 6300 CPU, Nvidia 660 gtx with driver version 343.22, and I have 8 Gb of DDR3 RAM.. Full Specs

Reproducible: Sometimes

Steps to Reproduce:
1Fresh install of kubuntu 14.10 with multiple monitors.
2.Open all my working programs
3.Start working

Actual Results:  
plasmashell will occasonally start spiking memory usage and calm down.

Expected Results:  
not hog 500 MB of memory

Can you identify the steps leading to that sudden memory spike? When your mouse starts stuttering, can you check what process is hogging your cpu?

Comment 2 Lane Wiscombe 2014-12-24 19:44:39 UTC

Dan, high memory consumption caused by Qt 5.9 updates with slideshow images are tracked at bug 381000. If you do not use the slideshow wallpaper, please report a new ticket.
