I like to let Librecad do frequent autosaves, so I set it to one every minute. Since my update to Ubuntu 18.10 an inconvenience occurred.
Normally the status bar has two "lines", as seen in the image below:
During autosave however, the status bar only has one "line":
The unpractical effect is that every time Librecad is autosaving, the drawing "jumps" "one line" down and up.
(The cursor is at (0,0) in the first image, but at a higher point during autosave). Quiet annoying, especially when you want to click somewhere at that moment...
Presumably, this is caused by the Qt libs which come with Ubuntu since 18.04.
One issue, the extra wide layer list columns, was solved recently.
Seems they have changed some default behavior of UI elements in Qt.
On my system the auto save message is one line too, but it doesn't shrink the status bar.
So I can't reproduce it yet, but I understand the issue.
I opened a github issue to track this.
