Description Andre Woebbeking 2012-09-08 12:12:50 UTC
I compile 4.9 from branch. Since yesterday I've the problem that the active window is a bit transparent but I configured transparency only for inactive or moving windows. You can see this best in parts of the window that are painted with QPalette::Window color or if you scroll in e. g. Konqueror or KMail. Then it looks like a composite of the last and new content.

Reproducible: Always

I forgot to mention, this doesn't happen if I disable all effects.

see https://git.reviewboard.kde.org/r/106335/
try "!isInactive(w)" -> "isInactive(w)"

Drop supperfluous and wrong inactive check in translucency effect

Left over from the cleanup which basically resulted in the active window
being put to the inactive's window opacity.

Thanks for the early notification of that issue.
FIXED-IN: 4.9.2
