According to bug 978338#c10 and bug 980014 this behaviour is intended. The tiles have fixed size and if there is not enough space to display them, the number of rows/columns is reduced.

I've set mine with 6 columns and 5 rows, which can easily fit to my window, and since 3 days ago, it shows me 6 colums and 4. It doesn't even show 5th row when I zoom it out, and it changes it to 5x5 instead... I just want my 6x5...

Giant thumbnails are unnecessary for me, I intentionally increased my row/column count. Is it at least possible to change size of tiles or is it fixed?

How about auto-zoom ?
