Really thanks devs for the new version of wallet. It is super to see that the development is going forward. But this new wallet is the worst I have ever seen for syncing. It was not able to start with datadir files synced from previous version (keep crashing). I deleted whole contents of datadir except my wallet.dat and let it sync from the scratch. But it is not able to do full sync. It is doing OK for several minutes and after that stop at random block and for hours nothing after that. Log file contains ten thousands of lines with this:

I have to close wallet, delete generated log file (it is prety large) and start it again. It can continue in syncing again after that. But it stops on another random block again. So have to close and start it again for syncing another blocks until next stop ...
Running on i5-3470, 16GB, SSD, Win8.1, 1Gbps symmetric connection. Previous wallet was well working.
