Just testing upgrade form 2.3.3 to 2.3.4 and noticed there is an issue with ImageMagick display of product images. On category pages some images are missing and on product view page no images are appearing at all. Reverting to the php gd image processor in backend resolves issue and all images appear correctly (apart from png image with transparent backgrounds which appear black - reason for using ImageMagick). ImageMagick is correctly shown in phpinfo and seems to be working fine for 2.3.3 which installed on same server.. any ideas? running php 7.2 on centos 6.
