Sometimes doing things that no sane person would do gives insights. Othertimes, it just hurts more.
For some odd reason, it seems to be behaving exactly the opposite of how it was behaving initially as far as "Copy To Texture", but maybe I had it in a different state when LyX started up. The following tests were done by setting the given settings, loading LyX, opening a 100+ page document, scrolling up and down a bit, and then starting a new paragraph and banging away like a mad monkey and seeing how well it keeps up. I also looked at scroll speed and ended by typing a sentence to see if it was in a "losing keystrokes" state. If it couldn't keep up, it was marked "Slow", if it kept up, it is "Fast". Sometimes, the performance would change and get slower or faster, and I tested everything again when this happened. Sometimes it would get to the point where it would lose keystrokes - it actually looked like some sort of buffer overflow. Once it loses a keystroke, you have to hit a key to get the one it lost. I marked Bug #1329082 <https://bugs.launchpad.net/bugs/1329082> as a duplicate as this is definately what I was seeing before. I'm 80% sure these problems don't appear on the binary ATI driver, but I'm not willing to re-install it to find out just yet. Getting rid of it was like pulling teeth. Most Consistent Results: ---------------------------------- Copy To Texture ON ON OFF OFF use_qimage false true false true Speed fast slow slow slow The only winner seems to be to have qimage to false and copy to texture on. Anyone else want to verify this? On Tue, Jul 22, 2014 at 9:37 AM, Jean-Marc Lasgouttes < 353...@bugs.launchpad.net> wrote: > I would not try to change compiz settings while LyX is running.
