I found a bug related to Drive Map and Cluster Inspector.
The bug was not present in v16.0.345, it appears in 16.0.367 and exists through all 17.x.x versions and is also present in the newest v18.0.39.
Bug probably happend when fixing 15665 and 15762 issues of v16.0.345 (Just looking into changelog of v16.0.367).
What's going on:
Here is printscreen of some disk map:
With the default colors, shaded and default block size, when double click to white block (really white, not dirty), there should be "Free" area displayed in Cluster Inspector, like this:
But, as you see next, the block map looks like shifted few (five?) blocks forward, and cluster inspector shows not free, but data:
And conversely, when click to used (blue) block, there is free space instead of data:
Next few images to understand the situation (actually one file, next empty gap, next another file):

When switched to 3 pixels view, this shifting is huge:

After downgrade to v16.0.345 or earlier, all blocks in the map perfectly matchs / fits cluster inspector information:

Disk map and Cluster inspector are very useful things, but must match each other, otherwise causes confusion.
I believe, this is only little mistake, typing error or something like this in the programming and should be easy to fix.
It will be great if fixed in the next release. :-)
Danke schön!
