The scroll position is not restored after the viewer is updated, for example after collapsing some quotes or after the signature was verified. See code in ViewerPrivate::updateReaderWin().
How to collapse some quote ?
If you have qouted text, like > bla bla bla > bla bla bla Then a collapse icon should appear.on the left of the text. It needs to be enabled at Settings->Appearance->Message Window->Show expand/collapse quote marks first.
Ok I can confirm this bug Will look at how to fix it.
void MailWebView::scrollToRelativePosition( double pos ) { // FIXME: This doesn't work, Qt resets the scrollbar value somewhere in the event handler. // Using a singleshot timer wouldn't work either, since that introduces visible scrolling. const int max = page()->mainFrame()->scrollBarMaximum( Qt::Vertical ); page()->currentFrame()->setScrollBarValue( Qt::Vertical, max * pos ); } ok it's a known bug
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kdepim (version 5.0 or later, as part of KDE Applications 15.08 or later), it gets closed in about three months.
Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
