Created attachment 164812 [details] pptx This pptx [originally MSO generated, having Calibri font] has text displayed differently when opened in LO even when substitute fonts [Carlito, since I don't have Calibri] have same metrics. Due to same metrics, it should have been exactly similar, I expected. See that at the end of one/multiple lines, one/few words either have been pushed to next line or extra words have been included in the line. I'm uploading this side by side comparison for only few of the slides via gif Version: 7.0.0.3 Build ID: 8061b3e9204bef6b321a21033174034a5e2ea88e CPU threads: 4; OS: Linux 5.4; UI render: default; VCL: gtk3 Locale: en-IN (en_IN); UI: en-US Calc: threaded more details in discussion at https://ask.libreoffice.org/en/question/261699/powerpoint-compatibility-text-not-displayed-identically-even-when-substitute-fonts-have-same-metrics/
