This is incredibly weird. I added the line to preferences ...
If I start with Copy To Textures off, its OK an I can turn Copy To Preferences back on while Lyx is running and it looks like the preferences line has fixed things. It looks very quick like this. I then turned Copy To Texture back off, as it was when I started it. Its worse than ever! I turn copy to texture back on, and its back to being slow (like before any of this started). Turning off Copy to Texture fixes it again. If I start with Copy to Textures on, it looks like the preferences change has fixed it. I turn Copy To Textures off, and now its so slow that it misses keystrokes (see Bug #1329082 ) - a bug I haven't been able to replicate, but can do so following these steps. LyX now has to be closed. You can't use it no matter what I do to CopyTo Textures. Removed added preferences line ... I started with Copy To Texture off. Slow. Turning it on now invokes Bug #1329082! Its like keys are getting stuck in the event buffer. Old keys come out that were missed when typing new ones. Very strange. Restart with Copy ToTexture on. Fast. Turning it off. Still Fast. Back on. Still fast - nope - gave it a minute ... slow again. Turning off copy to texture fixed it. Apparently, the preferences change has some effect on this, Copy to Textures has a dramatic effect - both at the time LyX is started and the current state, and how long your using it. Its at least 4 different factors. I'll keep playing with this later. Any ideas on specific tests you'd like me to try? Its hurting my brain!
