Re-saving as PPTX with LO before exporting fixes the issue. Using the impress_pdf_Export filter, I bibisected with linux-64-7.5 repo to first bad commit caee3eee4bab84fb7e7f438ea1ff43496414f096 which points to core commit: commit 60fd694ac362e9314f54fa992e31e8baa5bdf80f author Khaled Hosny Tue Sep 06 00:56:37 2022 +0200 committer خالد حسني Tue Sep 06 15:05:39 2022 +0200 vcl: Add LogicalFontInstance::GetGlyphWidth() To be used it in PDF export where we need the unshaped glyph width to calculate PDF glyph adjustments. Reviewed-on: https://gerrit.libreoffice.org/c/core/+/139462 At this point, only two characters out of five are visible on the export. Later on, at build commit e02e4eac04b0750cdd4e82ee0d7962033ca96786, which points to the core commit below, they are in the wrong order, and two of them overlap. commit e5a797a9beb03b9d9759a94b98107f509a0d5488 author Khaled Hosny Sun Sep 18 13:04:05 2022 +0200 committer خالد حسني Mon Sep 19 13:38:52 2022 +0200 vcl: Fix Type 3 glyph widths Reviewed-on: https://gerrit.libreoffice.org/c/core/+/140126 Khaled, can you please have a look?
(In reply to Stéphane Guillou (stragu) from comment #5) > Re-saving as PPTX with LO before exporting fixes the issue. (for some reason, this is only true after _deleting_ some other slides and then saving, but not if e.g. moving a picture or editing some other text and then saving...)
