libpng warning: Incorrect bKGD chunk index value

[michel-thomas]

Another strange error with OnlyOffice about libpng this time!

My configuration is:

• Nextcloud 19.0.3
• PostgreSQL 11.9
• Nginx 1.14.2
• PHP 7.3.19
• ObjectStorage S3 as primary storage
• app OnlyOffice 6.1.0
• app Community Document Server 0.1.8
• memcache.local =APCu, memcache.distributed and memcache.locking = Redis

Have you seen similar errors? Can't find other than this old issue without solution (server#16707): php-gd and php7.3-gd are installed.

Thanks for your help!
