Running on a machine with Ubuntu 10.10 64bit and Lyx 1.6.7 as well as 1.6.8. Not sure if it's the same bug, but in my case, I isolated the problem to a simple procedure: Close everything (best to reboot) and start up only your LyX file. Scrolling and writing should be fast even with big documents. Hit the "View PDF" toolbar button to compile it. For me it opens up in Evince. Now go back to LyX (alt+tab or click the window list), scrolling and writing suddenly becomes very slow. Minimise the Evince window, then minimise and unminimise the the LyX window - everything is fast and smooth again. It stays fast as long as the Evince window is minimised so far, will have to investigate further.
Very strange behaviour... this workaround behaviour works for me but I can't explain it. Hope it helps someone else... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/353449 Title: lyx 1.6.x impossibly slow -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
