The theme of the mouse cursor partially fails after logging in for the first time with a new user account (i.e. no configuration, empty home directory). In particular the cursor for resizing a window fails and is replaced with some default X cursor (see attached screenshot). It works fine after switching to a different cursor style and back to the initial one. Reproducible: Always
Created attachment 95537 [details] Screenshot of a kmines window with the wrong cursor in the lower right corner. A screenshot of kmines when trying to resize the window. As you can see, the cursor is not the cursor of the default theme (Breeze) for resizing a window, but the unmodified X11 cursor.
Which distribution are you using? The problem here is that the distribution has not set up the default cursor theme properly causing a fallback to the default X theme in kwin.

I am using Gentoo with testing (~keyword) packages from the kde overlay. It does not help to log out and log in again. I actually need to set the cursor theme. What I have also recognized now is that the cursor for resizing a window in the lower right corner appears if I move the cursor further to the center of the window. At a position I definitely would not expect to allow resizing any more, the proper cursor is still there (at least in kmines) and I can resize the window, although it then becomes the wrong cursor again while dragging the window frame. That sound a bit confusing, but I guess it becomes clear when viewing the attached screen capture. I would not have expected this to be a distribution problem. Are your sure? What could go wrong there and how can it be fixed?
Can you recreate it on a more recent version of your distribution? Looks exactly like Martin has said - fallback to default theme because of incorrect setting up this by distribution. I can confirm it all looks fine in Debian 9/Plasma 5.8 and Neon Git Stable/Plasma 5.12 using a new, fresh user with clean configuration.
(In reply to Edmund Kasprzak from comment #4) > Can you recreate it on a more recent version of your distribution? No, I can not recreate it any more with recent packages. This seems to be fixed. (Downstream I guess?) Anyway, it is fixed, so I close this bug.
