Description Jamie Macdonald 2014-04-12 00:24:01 UTC 
Version 4.12.4

When "Switch Desktop on Edge" is set to "Always Enabled", in "Workspace Behaviour"->"Virtual Desktops"->"Screen Edges", and the hot corners are not in use, moving cursor to a corner will trigger the switch desktop and cursor will pop out of opposite corner; 

e.g. if you move cursor to top right corner, it switches desktop and comes out bottom left corner.

Expected behaviour: cursor comes out of top left if gone into top right, and bottom left if gone into bottom right & vice versa to be continuous with what happens otherwise.

Reproducible: Always

This most likely depends on your desktop layout.
Comment 2 Thomas Lübking 2014-04-12 15:40:47 UTC 
Jamie, can you please provide the output of

kreadconfig --file kwinrc --group Desktops --key Number
kreadconfig --file kwinrc --group Desktops --key Rows
kreadconfig --file kwinrc --group Windows --key ElectricBorderDelay
kreadconfig --file kwinrc --group Windows --key ElectricBorderPushbackPixels
kreadconfig --file kwinrc --group Windows --key ElectricBorderCooldown

Thanks.

I think maybe I understand, if the layout were more than 1 row, the corners would move along the diagonal?
Comment 5 Thomas Lübking 2014-04-12 19:47:51 UTC 
is the layout, yes.
