Since the 126.96.36.199 release, the screen is flashing and sometimes the application freeze definitivly. (Windows 7 pro with NVidia Quadro 2000M)
The font used for the menu is a bold one !
No more problems when I'm coming back on release 188.8.131.52 !
I have notice that some fonts are no more include on version 184.108.40.206, why ?
Tks for your fantastic work.
Steps to Reproduce:
1. Immediately when the windows open
Libreoffice windows flashing and freeze.
No latency, no flashing
User Profile Reset: No
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0
Those fonts are bundled. If they were removed during install you now have a bad/incomplete installation.
First, check the .MSI install package size against the HASH value listed in the "details" MirrorBrain meta file for the build . That will assure you the package is complete.
Then, do a complete uninstall of LibreOffice. And check that the LibreOffice provided fonts  are all gone (the LO uninstaller should remove them when the ref-count reduces to 0).
Perform a fresh installation of LibreOffice, I'd suggest you capture an installation log--so the install must be from a command window.
Use the command:
msiexec.exe /i LibreOffice_220.127.116.11_Win_x64.msi /L*v install5332log.txt
Check the result, look at the installed fonts and run LibreOffice. If still issues, please ZIP the install log and attach it to this bug. If all is good please close as WORKSFORME or INVALID
I have completely remove the 18.104.22.168 and install the 22.214.171.124 release.
Same problem : the menus of Libreoffice are flashing when the mice arrow is flying over, they whispered and reappear !
When I came back to the 126.96.36.199 (x86) release, the menus refreshing is ok.
There is no problem with the fonts. The same are present with the 2 release.
