Graphic glitches when renaming items or making new folders

This is a fun one, and very difficult to replicate and capture.

Ever since the switch to x64, I noticed small rectangles flickering in the tree when renaming items in the list or making a new folder. I found that one of the glitches is the file length being rendered in multiple places:

This happened when creating "New Folder-03" and shows (a) the file length of that folder in the correct location, and (b) the file length of "mNew..." at the x-coordinates of "New Folder-03" and in the tree.

Replication is very difficult and even with the right configuration it often takes multiple tries to trigger this glitch. To exclude my system doing something strange, I loaded up a Windows 10 VM. I tested XYplorer 28.30.1300 x64 on Windows 10 with screen scaling at 100%. The latest 28.30.1400 seems to be affected too.

1) In a fresh XYplorer installation, change "RenameShowLength=1" and "SelSpecHeight=500". I saw the glitch with other values for SelSpecHeight, down to "35". Don't know if the other "SelSpec" trigger the glitch as well.
2) Drag the list border all the way to the left.
3) Do a slow double click on a folder in the list.
4) Without finishing the rename operation, drag the list border to the right.
5) Click on the "New Folder" button.

I noticed that the size of the XYplorer window may influence how often it glitches, and where the list border gets dragged to.

Here is what it looks like:

On my working configuration, I also see an empty rectangle glitching in the tree when I rename an item directly after starting XYplorer and without having to drag the list border. It is placed like the file length, but it's empty (I removed the folder names for privacy reasons).

Yep, I can see it, too. Fixed in next beta.

So far, v28.30.1401 is glitch free, awesome!
