If I select icon(or more) on desktop xfdesktop will use 100% of a core(~36% total on i3-3220).
Created attachment 8852 strace of xfdesktop while consuming 100% of cpu core(icon is selected)
Created attachment 8853 strace with stacktrace of xfdesktop while consuming 100% of cpu core(icon is selected)
Did you notice this issue with previous releases? If not, are you able to bisect? A random guess: can please you also try another theme?
Do not noticed on older version, but the issue appears to be theme related. If I go to Settings Manager -> Appearance -> Style, issue is only shown on Adapta-Eta-Maia, Adapta-Maia, Adapta-Nokto-Eta-Maia, Adapta-Nokto-Maia. Other styles are not affected, thus ok.
I tried that theme (3.95.0.11 from Arch Linux repository), it not as ugly as reported, my CPU goes up to 7% when icons are selected. From the stacktrace, I saw many occurrences of xfce_desktop_get_cycle_backdrop, I thought that the Next Background option introduced in 4.13.5 could be the culprit, but with 4.13.4 I get the same increased CPU usage. Well, I will let this bug open, but I don't think this is an xfdesktop bug, instead it's a theme bug. Even the panel looks weird here with Adapta, it's like there is an 1px transparent border.
Andre, what CPU you have? If 8 core/16 thread one, than can be down to 7% of total CPU usage. As far as saw(on my desktop), xfdesktop process consumes whole cpu thread. I will try to contact some Adapta theme dev to see if we can fix this issue.

Were you able to contact the Adapta theme dev(s)?
no, but in process of getting to contact one(Tista - https://github.com/tista500)

Some more information, including a workaround, at this forum thread: https://forum.xfce.org/viewtopic.php?pid=55613. Not sure what the cause is, but setting the active icon background to transparent seems to bypass the issue.
