Poor print quality since upgrading to Cura 3.2

I recently upgraded Cura and have problems with the print quality.

In the first photo The PLA filament is not smooth like it was before. It is bumpy and ragged.

The second photo shows the barrel of Bergerman’s WW 2 Hetzer. The barrel is not smooth and is misaligned.

I would appreciate any suggestions you can provide to improve printing quality.
