Lyx awfully slow and unresponsive

Postby TMorville » Mon Nov 18, 2013 2:17 pm

I've just aquired a new MBP through work.

I've been using Lyx for a year, but im new to the OSX platform.

My problem is that Lyx is awefully slow. Scrolling is a pain, and it seems to lock up the entire PC while opening a relatively small (10 p) lyx document. Its almost unusable.

I've googled this, and found that some people have similar issues. Ive tried the following:

I installed the newest MacTex package, and i've tried 2.0.0, 2.0.4 and 2.0.6 (newest) versions of lyx. Using AppZapper to remove them between upgrading. A colleage of mine is using the same version of OSX with lyx 2.0.4 - and that works fine...

I found this on a forum:

" may add the following line to your preferences file:
\force_paint_single_char false
On a Mac this is the file "~/Library/Application Support/LyX-2.0/preferences".
(Broken cursor placement for long lines should be one consequence.)"

but when i access that path on my PC - theres no preferences file?

So, any and all input is welcome.

Thanks in advance

I found a solution.

Lyx is out in a beta version 2.1 (beta 2).

You can download it here:

and that helped alot. Its still not windows standards, but it sure did work.

I have a similar problem. I run Lyx 2.3.0 on macOS High Sierra. Lyx is very slow when it comes to typing and editing. Does anyone have the same problem? Is there any solution? Thank you!

I haven't seen this problem on Ubuntu. You might try LyX 2.3.1 which will hopefully be released in a few days. Maybe it will somehow fix the issue you're seeing.

Return to “LyX”
