vkbd: Kirigami app window glitches for a frame when keyboard is opened/closed
I think the main problem is that KWin doesn't resize the window prior to the vkbd opening, so for a split moment the keyboard shows up over the app. Kirigami apps reserve a space in the application footer for overlaid virtual keyboards, which sees the overlaid keyboard for a split second before KWin resizes it to be above the vkbd.
As a related/unrelated sidenote, I opened https://github.com/maliit/keyboard/pull/211 against maliit to change the "swipe down" gesture so that it doesn't change the keyboard geometry, which should make it much less glitchy.
