Hi Martin,
I found the same bug as you mentioned
https://bugs.kde.org/show_bug.cgi?id=333511 I experienced it several
months ago, but due to some reasons (a lot of projects) I do not have
time to fix it ;(
Today I diff the g...@git.kde.org:kwin tabbox/tabbox.cpp and
kde-workspace-4.11.13/kwin/tabbox/tabbox.cpp they are almost the same
except QAbstractNativeEventFilter and Qt5`s migration, for example,
Workspace::workspaceEvent(xcb_generic_event_t *e)
And sorry for my mistake, it is not m_delayedShowTimer`s issue!
I have no idea why item->setVisible(true) did not work for the first
time Alt+Tab keyPress, but keyRelease, then pressed Alt+Tab again, the
SwitcherItem was visible!
