@kovid: the problem happens because gui2.library.views.restrict_column_width() is called before the main window is resized. At startup the (undisplayed) main window appears to be 100px wide so the calculation of the maximum space available for a column is incorrect. The sizes don't become correct until all the various events are processed, which is at the end of initialization.

I have a fix but I worry that it is not optimal or even correct. I changed restrict_column_width() to do nothing until all of the events to repaint the screen are processed (the same as quickview initialization). This required added an "initialization_complete" boolean to ui.py that restrict_column_width() checks. I can push a PR with these changes if you want to see them.

Edit: restrict_column_width() appeared with pin views.

Edit 2: my guess is that Qt changed how and when some resize and repaint events are processed.

EDIT: see post 19 below
