This is a regression that happened with the last daily snapshot: Version: 26.2.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: fd48da7236f26d9d8d16759546a5c860f91b82de CPU threads: 12; OS: Linux 6.15; UI render: default; VCL: gtk3 1. Open attachment #160098 [details] from bug #132539 2. Enter presentation mode. 3. Observe how the two circles render totally different than with earlier versions of Impress or in Edit mode. This looks a bit like bug #167893. It is a different issue, though. The build above processes bug #167893 properly. Earlier builds that get it wrong, get this new issue right. (I would not be surprised for the fix for bug #167893, bug #167879, and bug #167876 to have triggered this.)

Thank you for addressing this and the previous regression so swiftly (on top of the original improvement to begin with), Noel! Happy to confirm this as addressed with the last -dev build: Version: 26.2.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: 764799befcb927f68f78e904213e3db7195554cb CPU threads: 12; OS: Linux 6.16; UI render: default; VCL: gtk3
I'm just a bit nervous seeing we seemingly do not have any regression tests that would have caught this bug (or bug #167893, bug #167879, or bug #167876).
