Most likely in Qt. I had seen this once in kate as well and it looked to
me like either Qt is not updating correctly (single buffering?) or what
I consider more likely this is a tooltip issue. At least in dolphin I
see that tooltips open and are not properly marked as a transient. If it
is now under the mouse we get flicker, because it opens, gains focus and
dolphin then destroys it again and the complete process repeats. I hope
that the Qt 5.9.2 fixes that.
Otherwise I suggest to run these apps on xcb platform. As mentioned in
the thread about QT_QPA_PLATFORM env var I have the feeling that xcb
platform just works better for many apps.
