CPU Spike

Open arkonbob opened this issue 5 years ago • 5 comments

When I enable this, CPU usage jumps from around 25% to over 60%. I'd expected there must be some overhead, but that would be a deal-breaker for me. Is that normal or is there something amiss on my system?

Something is definitely amiss. I've got this installed on 4 different machines, and don't notice that.

Can you provide your system information? KDE/Plasma Version CPU RAM Graphics Card

etc?

Actually I've just re-enabled KDE-Rounded-Corners and I'm not able to reproduce the issue, there's no longer any discernible overhead. Looks like I should have tested more thoroughly after a reboot. Apologies for the time wasting and thanks for the response. Rounded windows looking good here :-)

FYI in case it does come up again I'm on an Acer R7-371T laptop: Operating System: Kubuntu 18.10 KDE Plasma Version: 5.15.3 KDE Frameworks Version: 5.54.0 Qt Version: 5.11.1 Kernel Version: 4.18.0-16-generic OS Type: 64-bit Processors: 4 × Intel® Core™ i7-5500U CPU @ 2.40GHz Memory: 7.7 GiB of RAM GPU: Intel HD Graphics 5500

I definitely see a CPU spike from 30% to 60% CPU usage when moving a window in kwin_x11. I'm on a Intel Core i5 7200U. That's quite high for rounding corners.

Oh, the reason I looked into CPU usage, by the way, was that when running zoom, CPU is more than DOUBLED (!!) with this effect enabled while running Zoom (from about 70% to 150% on my Kaby Lake Core i5).
