Created attachment 202091 [details] Archive with some Impress template files When a directory containing the attached set of custom templates is set as default template location, the Master Slides sidebars "Available to Use" list shows incorrect preview - depending also on UI language (English: the Default empty slide, German: one of the files). This seems to happen because the different files have the same name (Default) for their first master slide, and this somehow confuses Impress to think they need the same thumbnail image. 1. Unzip the attached file into a directory 2. In Options -> Paths -> Template set the target directory as a template source, restart LO 3. Open a new Impress document 4. In the Master Slides sidebar look at the Available to Use section -> Several templates (tooltip says: CT-22, CT-23 and CT-24-Mod) have the same thumbnail image, but CT24 has a unique thumbnail. The difference between the CT24 and CT-24-Mod templates (the files conference-template-luxemburg.otp and conference-template-luxemburg-mod.otp) is that CT24 has the original name of the first master slide (Padrão - which may be a translation for Default) and in CT-24-Mod I have changed this to Default, which is the same as in the other two templates with incorrect thumbnails. Version: 26.2.0.0.alpha0+ (X86_64) / LibreOffice Community Build ID: 7f4868348c14b305fcd75744e1e3544d0d3a5d61 CPU threads: 14; OS: Windows 10 X86_64 (build 19045); UI render: Skia/Raster; VCL: win Locale: hu-HU (hu_HU); UI: en-US Calc: threaded already worked like this in 3.3, no regression here.
