This is exactly what was happening in my case. I was using a theme where 
the OS (Windows 10)  background picture and colors change automatically 
every 3 hrs. Initially, I could not figure out that the freeze+memory 
leak is caused by the MS Windows background and color changes. Then, 
just by chance, I was able reproduce the leak, when I change the MS 
Windows theme color manually. I think you can also re-generate it 
easily: Open LyX. Go to Windows settings. Go to Themes. Change the color 
of the theme. Observe LyX and memory usage from Task Manager.
