Kicker: Popups sometimes show items of former category #10

Closed star-buck closed 9 years ago

I think this is a driver-related rendering issue that sometimes causes old window/texture/whatever contents to be painted. I could sort of reproduce it on my Intel/Mesa laptop (along with some rendering artifacts), but it's not happening on nVidia, and the model backend is correctly announcing new data. The only workaround from the Kicker side would be to give up on reusing the dialog and create a new dialog every time, which however would make Kicker much slower for everyone with non-broken drivers, so it's a frustrating situation and I'm not sure what we should do.

Here's the relevant Qt bug report, which was closed as out of scope due to bug in Mesa: https://bugreports.qt-project.org/browse/QTBUG-39182
