Often when I bring up the Overview Grid, the mouse cursor goes missing, which make it rather difficult to use.
I use X11 and I just noticed while writing this up, that it seem that the mouse only goes missing if the mouse was in an X11 window at the time I bring up the Overview Grid.
If this is the case, I can probably just train myself not to do that. But it would be even better, of course, if it “just worked”.
P.S. I’m using TotalSpaces2 v2.6.24 on Sierra Version 10.12.6.
