XFCE desktop - system icons themselves arrange off the screen

[Stevan Kew Ell]

When clicking "Arrange Desktop Icons" in XF Desktop properties, the system icons, Home. Wastebasket and Removable Devices (I don't use the additional "Filesystem option) arrange themselves off the screen area to the left rather than at the top left and visible. A tiny portion of an icon is just visible, provising a clue as to what has happened.
A workaround is to choose "Desktop Settings", the Icons tab, and un-select and re-select the system icons. when they appear at the end (bottom right) of the desktop, or tolog out and log back in, which arranges the icons in a half-expected manner.
This issue may account for some reports of invisible disk mounts on the desktop, where the mount icons may simply be off the screen.
Additionally, the icons do not sort themselves into any sensible order.
The expected action is to arrange with known icons first, followed by folders, followed by files in alphabetical order, but the arranged order appears to be random.

Correct Arrange of Icons

Looks like a misplacement bug has shown up between 4.11 until 4.12 final release. I'm using XFCE 4.12 from Fedora COPR and saw a misbehaviour when pressing "Arrange Desktop Icons". The icons magically disappear, get aligned elsewhere, show up again, go away and so on. The only way to get them back is going into "Desktop Settings -> Icons -> Change Icon Type to something else and then back". Attached 3 Screenshots. This didn't happen with 4.11, so this must be a quite close recent change inside GIT.

After changing Icon Type and then back. The Trashcan icon is missing.

Please note: It may be necessary to try this when using the desktop for quite a few hours. I also have an external Monitor that I turn on and off whenever necessary.

So, after rebooting my PC, I can post an update here. Having following commit included, the icons don't jump of the edge anymore. Only Trash and Filesystem will disappear. You have to press F5 to get them back:

Thanks - thought it was just an issue here, never totally sure of the state of my system. Reported upstream too.
