The following regressions are new in the rewritten desktop grid effect in 5.25 - There is no visual indicator of which virtual desktop is currently chosen if you switch them via keyboard (or mouse), other than the focussed window in it being slightly highlighted. The desktop itself should be highlighted. - There is no way to completely deactive the present window effect, the only options are "closest" and "natural", there should be "none" which does only trigger desktop grid, and not also present windows
One bugzilla ticket per issue please. :) Can you please file another one for the second thing? *** This bug has been marked as a duplicate of bug 453999 ***
