Editor becomes sluggish

Hi again @kovidgoyal

I first installed v8.2, then updated to v8.5, which I am still on. (I don't install every update, maybe every second or third release) Ever since updating to the v8 line, I have experienced the Editor becoming very sluggish.

Sometimes I need to step through Regex Search and replace instead of change all. This opens xhtml sheets as I step through. As I am stepping through, I might spot other issues and quickly fix them.

I might have, say, 30 pages open. The editor then becomes very sluggish. Trying to move the cursor using arrows, and it takes a second or two for it to move. Trying to type (I type 50wpm) and the letters appear very slowly, maybe upto a second between letters.

I can then flip to other running programs on my pc, and everything is normal. Flip back to Calibre Editor and it is sluggish. If I flip to Calibre library and, say, edit metadata on a book it is not sluggish, but there is a very slight jerkiness when typing. I then need to close all the pages, close the editor, then re-open it and continue with my edits until it happens again.

I haven't seen anybody else report this. Any idea what could be causing this? What other info can I provide?

PC is i7-10700K, 32GB RAM running Win11

Thanks.

Reboot Windows into safe mode? Not restart Calibre in debug mode?
Ok, will do.

The problem is this efficiency mode. Get out of it. Because QT uses Chrome, the system thinks it's a Browser and sets it

No need for safe mode. This stupid efficiency mode is slowing down calibre.
