[Bug]: When moving cursor horizontally or vertically, the column/line numbers are lagging behind #3505

What happened?

When moving the cursor in CodeLite with keys horizontally or vertically, or when typing key repeatedly, the column and line numbers seem to be refreshed every 1-2 seconds. Therefore, it is practically impossible to precisely position the cursor, e.g. at specific line and column, without waiting each time until the counter is updated. I don't know of any other text editor that has this kind of input lag.

This could have be a regression after some performance optimizations in CodeLite. However, updating the cursor position is not a performance-intensive task, so in a production environment it should be updated as soon as cursor position has changed.

P.S. Despite this, CodeLite still remains sluggish, to a point of being unusable on Raspberry PI 5, when trying to edit any non-trivial source code files.

FYI, CodeLite revision 6eb52aaff1bb3b999001fbbf56f38bc844000c41 doesn't suffer from this.
