Description Walter 2019-04-04 20:29:30 UTC
Description:
LibreOffice stops responding when I load NexusFont. When I close NexusFont LibreOffice regains control after about 1 minute.

I suspect that it has to do with the Fonts

Steps to Reproduce:
1. Open LibreOffice
2. Open Nexusfont

Actual Results:
LibreOffice stops responding

Expected Results:
LibreOffice should continue responding


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Unable to reproduce on Windows 10 Pro 64-bit en-US (1803) i7-7700K with 32GB ram and admin install of a 
recent master/6.3.0.0.alpha0+ Build ID: ce01727e4d6779ea128aa1be09f4af8cad4e1854 and the 3rd party NexusFont v2.6.2 Windows font manager.

Using an <F5> in NexusFont to load the Windows font cache for a moderate sized collection of fonts ~50 did cause LibreOffice to slow and show unresponsive--but once NexusFont and LibreOffice had parsed the newly activated fonts (they are not installed to system, rather NexusFont manages their mounts and unmounts and makes them available to applications) the added fonts were available to use in LibreOffice (Writer).

Closing Writer and LibreOffice then removing the folder of fonts in NexusFont caused no issue. On relaunch of LibreOffice, the fonts have been removed from the font list and show as not installed.

This all seems to work correctly if with a bit of delay on the LibreOffice side--can imagine the drag of parsing in a much larger folder of fonts.
Comment 2 Walter 2019-04-07 16:38:43 UTC
According to Nexusfont I have 553 installed fonts!
I have an i5-2450M CPU @ 2.5GHz, 6G RAM, Windows 7 64-bit
Nexusfont v 2.6.2
LibreOffice 5.4.7.2

In my case LibreOffice becomes completely unresponsive until I close Nexusfont and have to wait for about 60 seconds before it gains responsiveness
