--- Comment #15 from David Hurka <david.hu...@mailbox.org> ---
Git commit c6a3275151ffa5c9045c8186b64e45e4b2c3ccbf by David Hurka.
Committed on 20/11/2020 at 18:01.
Pushed by davidhurka into branch 'release/20.12'.
Fix QScroller crash on Qt < 5.14 and certain screen arrangements
QScrollerPrivate::setDpiFromWidget() before Qt 5.14 crashes
when the target widget does not intersect a physical screen,
because QDesktopWidget returns screen index `-1` in this case,
which leads to an out-of-range read from QApplication::screens(),
which leads to a segfault when reading from an invalid QScreen* pointer.
This adds a workaround that checks for the `-1` situation,
and then tries to resize PageView temporarily to intersect at least some
screen.
FIXED-IN: 20.12
