There seems to be 2 bugs with TreeGrid
Tested on Windows 7 with latest Firefox and Chrome
1. Scrolling bug - only in 10.0d, not in 9.1
When tree column is locked, showCustomScrollbars: false, and there is no horizontal scrollbar visible - if I scroll all the way down - last row only shows tree column cell and not the rest of cells. If I resize column - last row shows up again. And if I select one row before the last row and hit down arrow to navigate to last row - the row does show but tree column cell missmatches the other cells. If showCustomScrollbars: true - then everything works fine.
You can test with my code sample below.
2. Removing/adding as member -in both 10.0d and 9.1
In the code sample below I create VLayout with Window as member that has TreeGrid as item. I overwrote maximize/restore to de-parent Window with TreeGrid to maximize it to full screen. If I scroll TreeGrid down before maximizing, then hit maximize - it takes the whole screen just fine, however the scroll position is lost and is reset to 0. Then if I scroll in maximized grid down and hit restore to add Window with TreeGrid back to VLayout - not only scroll position is reset to 0 but also the grid shows only tree column parts of records and not the other cells - until I scroll or resize column - at which point the records show up again

fields.push({name: ''+ i, width: 150});
}
fields[0].frozen = true;
