[Octave-bug-tracker] [bug #45540] Segfault when moving the mouse over Qt figures

[Pantxo Diribarne]

Follow-up Comment #18, bug #45540 (project octave):

The patch I pushed was supposed to fix a very intensive use of GL_SELECT
mechanism (while hovering a window with the mouse)  introduced by this cset:

http://hg.savannah.gnu.org/hgweb/octave/rev/062422f2e399

... which in turn is on default. So the "fix" (more of a workaround) I pushed
is completely tied to default.
As bug #45683 is against 4.0, I suppose we should now find the root cause of
the segfault. Maybe some hardware specific driver issue.

@Michael: are you using the same family of graphics card as mentioned in bug
#45683 ? What does a grep in the source tree return, e.g.:


grep -rl "if (xlim(0) < p0(0) && xlim(1) > p0(0)" ./libgui/
