I have ran one game and my disk is containing some space in KBs. The installation of module download keep stucking and sometimes even screen is flickering.
Fixed a lot of underlying error handling issues, this should be working properly now.
The handling is better in this case, now -- you at least get the proper message about low disk space -- but there are still some UI issues that need to be resolved:
1) The progress dialog spawns on top of the error dialog
2) Clicking cancel doesn't actual cancel the operation
