If I set the animation time to 0ms, it uses a different code path that show the window properly but it doesn't set the focus to the konsole part: It shows the empty rectangle in the prompt, instead of the filled one. This makes copy&paste not to work properly and some other issues (although I can type just fine). Reproducible: Always Steps to Reproduce: 1. Open yakuake 2. change the time to 0ms 3. Close and show again
This doesn't seem to be specific to the xshape codepath, I'm seeing problems like this with kwin assist as well. *** This bug has been marked as a duplicate of bug 341330 ***
(BTW, just for completeness' sake: Taking the xshape codepath is unrelated to the animation duration, i.e. there were other reasons you ended up there.)
