Previously, I had two reading status columns: #read (tristate boolean) and #percentread (integer).

I recently updated all the templates I could find (column icons, composite columns, and some action chains) to check for a 0 or 100 in the integer column instead of true/false in the bool. All seemed to be well so I deleted the boolean column. Now Calibre is lagging every time I update a column.

I put back the boolean column and the lag went away completely.

My best guess is that I missed a template somewhere and it's trying to update based on the nonexistent column, but I can't figure out where it might be -- I scoured all my composite columns, and as far as I understand column icon rules remove themselves when invalid.

For now, just to kill the lag I just created a composite that returns 'yes' for 100 and 'no' for 0.

Any other idea where I should check?
