TabBox: Do not highlight selected window for fullscreen switchers
This helps improving performance on those effects, where the highlighted window is not even shown.
BUG: 449180 FIXED-IN: 5.25.3
Note that the updateHighlightWindows()
method seems to be quite heavy for every switcher
(at least on my set-up, integrated intel graphics card, where it means a high FPS drop
from ~60 FPS to ~30 FPS). Some improvements on this part would also be a general improvement
but I haven't profiled it yet.
