Description BRULE Herman 2017-07-31 18:22:01 UTC 
Hi,

Here I have slowdown after some days of uptime, kill and restart solve the problem. I put the profile here: http://ultracopier.first-world.info/temp/plasma-slowdown.tar.xz

Cheers,

Thanks for the report Brule.

I've not noticed any slowdowns with dual monitors and I've been using Plasma for about 8 months with no issues.

Can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved, thanks.

I remain with similar problem with LXQt + kwin. Maybe it's linked with Kwin? Maybe 2 unlinked problem. 3 years after this bug report... I don't use KDE for now. I have this kind of problem since KDE 4... with all kind of hardware (Intel/AMD, video Intel/AMD)

Thanks for the info Brule, I'll move this to kwin as it's happening with LXQt as well.

Performance is something we're constantly improving over time. The perf information is now outdated and there is nothing unique in this bug report that keeps it actionable.
