Example of rename issue and scrolling after to show that text box is in the same position, it just did not move with scroll:

Note I have only reproduced this in "List (by Album)" mode. "List" mode and "Browser" mode do not appear to be affected, as these seem faster from a GUI response perspective.
This also happens more often when a reorder of tracks happen (I think because GUI take longer to update). I get the reorder renaming track title (sorted by album artist) since I am operating 2 sets of files (different directories, mp3 and flac) in the same album, so a reorder sometimes happens within the track number. A view with more albums listed also helps with reproducing.
This is more of an annoyance, I am only reporting because I ran into this rename issue 10 times today.
I have also seen where the previous track title will get copied into the next track (no <CTRL-V> used) when using F2 to rename (I have not seen this issue these when using mouse rename). This is not easily reproducible, you have to be really fast, though I reproduced it twice when running the above tests.
