FWIW here's a log.

Thanks for the report. This is a draw issue if you switch tabs while in a slow remote saving. I'll open a tracker to investigate a fix, although initial research shows this might be more difficult than it appears to fix.

Please be clear that "FTP save prangs repaint for the duration" regardless of remote saving's speed

I'll open a tracker to investigate a fix, although initial research shows this might be more difficult than it appears to fix.

I can imagine. PS The test machine's CPU is an Intel having 4 cores.

Thanks.
