#176 High CPU usage (Probably relatet to ID: 2915935)

[svs]

First of all: nice application :-)

But when I import the test.ascii, select all columns, plot a diagram with all graphs
and zoom a small region of the data, here the x-axis (org 0-60 to 5-8), the cpu usage
gets incredibly high and remains while the window is active.
The cpu usage decreases immediately when the complete range of the data is reseted
to (0-60 or 5-40).

x11-libs/qt-assistant-4.6.2

are installed for scidavis-0.2.4.

Maybe somebody encounters the same problem.

I'm seeing the same bug on one system but not on a second one, both using our universal Linux binaries. Possibly related to the Qt version installed (doesn't happen on a system with Qt 4.6.3), although I haven't checked this yet.

[Knut Franke]

Possibly the same issue described here:
http://sourceforge.net/tracker/?func=detail&aid=1904418&group_id=13693&atid=113693

I've attached a patch which should fix this, but I currently don't have a system nearby where I can reproduce the bug, so I can't test.

I can't seem to repro this. Knut, did you end up applying you patch to the current_stable sources?
