SE18 slow/irregular cursor movement
« on: July 31, 2013, 02:44:32 pm »
I'm noticing that sometimes, after using the editor for a while, the cursor movement becomes slow and erratic.  Moving the cursor either vertically or horizontally by holding down a cursor key results in cursor movement with slow updates.  That is to say the cursor jumps multiple lines or characters between screen repaints.

Whilst this is happening there are visible bursts of cpu activity by SE.  These bursts are not sustained high cpu usage, but are enough to indicate that something is happening.

When this happens, exiting and restarting SE corrects the problem and movement/updates happen at full speed.

We had an 18.0 refresh bug that is fixed in 18.0.1.  I suppose it is possible that is causing the problem.  To check, you could try shutting off the horizontal scroll bar (Appearance>General>Horizontal scroll bar).

I already have the scroll bars disabled because of the consuming lots of cpu redrawing issue. (Happy to hear that this is fixed though).
This seems to be something different.

I'm still using 17, and I've been seeing a similar (possibly identical) symptom for a long time now.
The longer I have 17 open, the more CPU it consumes while idle, and eventually paints begin to get starved.

Is your Preview window open? I had to close mine for a while now.

My Preview window is auto-hide at the bottom of the frame.
