Build Identifier: 20110916-0149 It does not happen when i use Compiz for some reason. However i have not seen any ghosting from any other program i use with or without Compiz. Reproducible: Always Steps to Reproduce: 1. Hover mouse over a method in top of the editor and wait for popup 2. use scroll wheel without moving mouse curser. 3. notice a "ghost" of the popup being stuck on the screen until editor area has been scrolled out of visible area
Created attachment 205055 [details] popup visible
Created attachment 205056 [details] part of popup remains
when I scroll the editor (using the mouse wheel) and a tooltip is up, I get a black box area in the editor. Silenio, can this be a different manifestation of the same problem ?
I have seen this many times in Eclipse and it is an issue in Luna on Linux. As others state, hover over an item in source to get popup, and operate scroll wheel of mouse. Looks like scroll operation is not cancelling the popup so the area is not repainted as it has scrolled away from its original position. Probable solution is to ensure that the popup is cancelled before executing the scroll operation. This is a fairly common thing for me to see and it's pretty annoying :(
I cannot reproduce this issue. IIRC there were some fixes for scrolling/drawing in Neon. Please file a new bug against 4.8 if the issue occurs on GTK3.22.
