Removing the large image on the master slide in PP solves the issue.

Even with the same commit

Version: 26.2.0.0.alpha0+ (X86_64) / LibreOffice Community

Comment 4 BogdanB 2025-08-26 12:19:55 UTC 
I do NOT reproduce

Ok with
Version: 25.8.0.4 (X86_64)
Build ID: 48f00303701489684e67c38c28aff00cd5929e67
CPU threads: 16; OS: Linux 6.8; UI render: default; VCL: gtk3
Locale: ro-RO (ro_RO.UTF-8); UI: en-US

Also ok with latest master
Version: 26.2.0.0.alpha0+ (X86_64) / LibreOffice Community

Comment 5 Gerald Pfeifer 2025-08-26 13:36:11 UTC 
Interestingly enough it does not crash for me with the latest
daily build:

   Version: 26.2.0.0.alpha0+ (X86_64) / LibreOffice Community
   Build ID: 248ff6232da4f7efa5b4365434d413ce653267d9
   CPU threads: 12; OS: Linux 6.16; UI render: default; VCL: gtk3
   Locale: en-US (en_US.UTF-8); UI: en-US

This is with a resolution of 3840x2400 in case this may make a
difference.
Comment 6 Timur 2025-09-09 16:28:36 UTC 
I confirm both the crash and the fix in Linux gtk3.
