Description Paul 2017-05-06 13:20:56 UTC

When using the wallpaper slideshow two consecutive images are shown at login.

The first image is shown for only a very brief period (blink and you'll miss it), the second image then correctly remains for the duration set by "Change every:", (which in this case is set to 1 hour, 0 minutes, 0 seconds).

The first image appears random, it is not for example the last displayed image.

This is consistent and repeatable.

This appears to be fixed by the patch authored by "Vova Mshanetskiy" in relation to High CPU Utilisation by wallpaper slideshow.

But this patch has not yet been applied, right?

Comment 3 Paul 2017-11-24 12:07:30 UTC

It appears this patch doesn't fix the issue.  It "fixed" it for myself probably due to running on slow elderly hardware :)

Comment 4 Alexander Mentyu 2018-02-06 18:14:35 UTC

Can reproduce in:

Plasma: 5.11.5
Apps: 17.12.1
Frameworks: 5.42.0
Qt: 5.10.0
Kernel: 4.14.16-1-MANJARO

The first image appears same at login - and then right after the first one - second image is random

Wallpaper processing was massively simplified and improved for 5.17. Can anyone who was originally experiencing this issue still reproduce it in Plasma 5.17?

Comment 6 Paul 2019-11-14 10:12:15 UTC

I've been using a static wallpaper image, but have now switched back to slideshow.

So far (although very limited testing) it seems OK.

Comment 7 Paul 2019-11-16 09:13:20 UTC

OK. I think it is safe to say this does indeed appear to be fixed. :)

Comment 8 Nate Graham 2019-11-16 16:01:10 UTC

Great!
