Created attachment 181792 [details] Sample slide (PPTX) Viewing the attached sample slide in presentation mode, the lines of the boxes with text renders much thinner/ligher in Impress than it does in PowerPoint. Version: 7.5.0.0.alpha0+ / LibreOffice Community Build ID: 4e2ce2a460458f17ee4360c45a2da2fc4b4d753e CPU threads: 8; OS: Linux 5.18; UI render: default; VCL: gtk3 Locale: en-US (en_US.UTF-8); UI: en-US ...all the way back to at least LibreOffice 6.4 it appears.

Note, this is on a HiDPI display (3840x2160 on 14 inch).
Confirmed using LO 7.6.0.0.alpha0+ (d993327eab0a2c9c8820c6528075b01de68b0ec6) and 4.0.0.3 / Ubuntu. Display is not HiDPI.
Created attachment 185011 [details] PDF output by Office Live Which version of PowerPoint do you use? I can not reproduce the problem with Office Live. Comparing the output with LO 7.4, and the latest 7.6 dev, The line size is the same. See how Office Live displays it: https://view.officeapps.live.com/op/view.aspx?src=https://bugs.documentfoundation.org/attachment.cgi?id=181792 I have tested both on a HiDPI screen with scaling, and a normal display.
I compared the output from Office 2007, and Office 2019 / Office Live for the same SmartArt layout. The result from LibreOffice matches the output from Office 2019 and Office Live. They all draw thinner lines. So, I am closing this issue as WORKSFORME.
I've been revisiting this repeatedly since it got closed as WORKSFORME since it did not feel as clear cut to me. In my tests with 24.2 alpha and PowerPoint/web version today the latter still renders the lines a bit thicker than Impress does. Not a lot, and definitely far less than on 2022-08-15 and in the Visual Comparison in attachment #181793 [details], but still. I'll keep this closed since the difference is hardly noticable now, still wanted to add this background in case someone stumbles over this report again.
