Re: Lyx sluggish on Windows 10
Fantastic, thank you very much! Is the fix in a git repository somewhere so I can try it out?

I googled the latter and found some references to it in connection with possibly similar problems ( https://forum.affinity.serif.com/index.php?/topic/51268-usermode-font-driver-host-freezes-computer/). I tried the "clean boot" mentioned in that discussion but it didn't change anything. Incidently on Ubuntu the CPU usage for lyx in "top" hits ca 30% when I type into an equation in the same document at the same speed, but there is no additional process that sees increased CPU usage and lyx remains responsive while typing, unlike on windows.

Lyx sluggish on Windows 10
Hi, Recently Lyx has been sluggish when typing equations and scrolling in moderately sized documents, to the point that it becomes very frustrating. Is this known to be an issue with current versions? I am using a fresh install of Lyx 2.3.2-2 on an up-to-date version of Windows 10 (Version 1809). On Lyx 2.3.2 (2018-12-20) on Ubuntu 18.04.2 LTS on a much older computer editing same document is very snappy. Best Regards, David
LyX freezes periodically
Hi, When working on a specific large document (about 50 pages as a PDF), LyX does a very annoying thing where it freezes for about 4-5 seconds about once a minute. It seems to happen more often when I am editing equations. During the freeze the screen does not update when I type. When the freeze is over whatever I typed during the freeze appears all at once. Here are the details of my setup: OS: CentOS Release 6.4 / Linux Kernel 2.6.32-358.18.1.el6.x86_64 LyX version: 2.0.6 It is a powerful computer (12 Intel i7 cores and 16gb of ram), and other applications do not freeze. When working on the same document on my laptop (Thinkpad running Ubuntu) the freezes do not occur. Does anyone have any idea of how to fix this problem, or at least how to debug it? I have downloaded the source code and tried to find the place where it gets stuck, but to no avail. Best Regards, David
