Scrolling causes 100% CPU Usage
« on: June 22, 2005, 12:25:54 am »

Is this normal?  I have no other programs running, and when not scrolling, MC is at 6%.   Scrolling is very slow and choppy in MC.  I have noticed that when scrolling over the scroll bar itself, the scrolling is dramatically improved versus when scrolling over the selection area itself.  Why is this?  I only realized this now because I never use the scroll bar to scroll.  It's so much easier to just scroll wherever the mouse is.  Also when highlighting up or down a list, the lists 'scrolls' very fast.  Why the discrepancy in scrolling speeds?

This seems trivial but when you have large lists, this makes a big difference!

I have a playing now template that displays scrolleable lyrics.  I just realized that the scrolling is also slow on this.  Pausing the music does not help either.  Swithcing between scrolling this field and a web page in Firefox is like night and day.  The lyrics template is just simple html, so this tels me the porblem is MC specific.

I've found scrolling to be slow and jerky in Library Browser.

No where else?

The tree view is the only thing in MC that scrolls very smooth like on a webpage.  Everything else is slow.  If only MC could scroll everywhere else like it does in the tree view. ;D
