I was able to reproduce the first attachment by dragging each of the column dividers on the Accounts page to the left so that all three had zero width. Once that's done I wasn't able to drag the divider back to the right. Quitting and restarting GnuCash restored the columns to their default widths. Is that what you're reporting?

Created attachment 373275 [details] Illustration of drag mouse pointer Interesting. I can't reproduce this on Fedora 29. That is, I can drag all dividers to the left so all columns are 0 width. If I then move the mouse close to the extreme left border of the header, the mouse pointer changes into a drag pictogram and I can drag the columns back to the right one by one. I can even double-click while the mouse pointer shows the drag pictogram and it will restore the column to its optimal width. I have attached a screenshot showing the location and mouse pointer change. In the screenshot I didn't hide *all* columns, but I did test that before as well and it works the same. Just to be sure we are talking about the same thing: are you dragging from the far left hand side of the column header or from the final vertical divider that separates the empty header space from the column with the pop-down arrow ? The remaining visible divider can't be dragged. It has to be done from the far left.
This is about the left-most column. If you drag its right edge all the way to the left so that it disappears you can't get it back. While the divider cursor does appear when you hover on the left edge it changes to a pointer when you click so that you can't drag on it. At this writing I can reproduce only on macOS. On Windows and 2 Linux desktops. I think it likely to be a Gtk treeview behavior rather than anything to do with GnuCash.
