SUMMARY
Sometimes in icon view, when there is a shortened multi-line filename and you try to scroll, if there is whitespace below the current text's position, Dolphin will leave overlapping leftover text without refreshing the view. I've attached a video demo but I am not too sure how to consistently reproduce this bug, except for the conditions as mentioned here. It seems to happen when the file has a long multi line name(at least 3 lines) and when the file extension is on its own 4th line. When the mouse leaves the file area and reenters it the view gets refreshed. I've attached a screenshot of the filenames without a bug for reference. 

It also doesn't seem to happen for filenames when the extension is not on the 4th line, as demonstrated in the video, which makes me question if the file extension is supposed to be on the 4th line at all.  

STEPS TO REPRODUCE
1. Have many files with long filenames, at least 3 lines long. The extension is on the 4th line.  
2. Scroll the view in such a way that the filename location has whitespace underneath it
3. Observe the glitch

OBSERVED RESULT
The filename is rendered in a glitched way

EXPECTED RESULT
No glitching occurs
