Bug ID: 432284
Summary: Krita idles at non-zero CPU/GPU usage if a selection
is active, when minimized
Product: krita
Version: 4.4.2
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: General
Assignee: krita-bugs-n...@kde.org
Reporter: pieterjan.bri...@gmail.com
Target Milestone: ---
SUMMARY
Presumably due to the ants animation around the selection area, Krita idles at
non-zero CPU/GPU when you have a selection active. Now obviously if you're
actively using the program this makes sense (has to play the animation
somehow), but when you aren't using it and have it minimized this probably
shouldn't be the case?
On my system this results in about 0.3% CPU and 2.5% GPU usage.
This is far from significant of course (I have many other programs that are way
worse offenders CPU wise) but it still isn't ideal for users on battery. Krita
does still get listed as "very low" power usage in Task Manager but I figured
every little bit helps?
Seems like just disabling the animation if the window is minimized might be
easy enough? Spotify does the same from what I can tell. Disabling the
animation when the window isn't in focus might be harder to justify since you
could simply be focused on a window on another monitor or such, but minimized
should have no such problem.
STEPS TO REPRODUCE
1. Create a new image
2. Hit ctrl+a to select all
3. Minimize Krita
4. Check task manager for CPU/GPU usage.
OBSERVED RESULT
Krita consumes about 0.3% CPU and 2.5% GPU 0 (iGPU) on my laptop.
EXPECTED RESULT
Krita to consume 0% CPU and 0% GPU like it does with no selection active.
