Bug ID: 436498
Summary: WindowSystem::window(WId wid) returns the wrong window
Product: kwayland-integration
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: fab...@ritter-vogt.de
Target Milestone: ---
It does this:
const auto &windows =
WaylandIntegration::self()->plasmaWindowManagement()->windows();
auto it = std::find_if(windows.begin(), windows.end(), [wid] (PlasmaWindow
*w) { return w->internalId() == wid; } );
wid is the internally generated window id in the client process, while
internalId() returns the internally generated window id from the compositor.
Those do not match, which essentially means that any KWindowSystem functions on
wayland which take a WId act on a random window instead.
krunner for instance calls KWindowSystem::forceActiveWindow(winId()); after the
window is shown, but actually activates the desktop (plasmashell) instead.
krunner's View is the first QWaylandWindow instance and gets winId 1, while
plasmashell is the first window created by kwayland-server.
