UPDATE September 12, 2023:  Windows 11 Users

We recently conducted extensive testing involving Windows 11, Zoom, and Slideshows to address an issue stemming from a recent Windows update. It has come to our attention that this update is causing complications when images and effects are rendered using OpenGL technology, which subsequently requires translation for transmission via Zoom.

OpenGL serves as a crucial software interface, facilitating seamless communication between programmers and graphics hardware for the purpose of rendering graphics in various applications and gaming environments. Within our ProSelect software, we utilize OpenGL to enhance the efficiency of rendering and incorporate visually appealing Ken Burns effects.

To address the issue you may be experiencing, we recommend following these steps:

1. Open ProSelect and navigate to Preferences > Slideshow.
2. Uncheck the option labeled "Use OpenGL."

Our comprehensive tests indicate that disabling the "Use OpenGL" option will enable Zoom to transmit your Slideshow without any complications. However, please note that if your Slideshow includes styles with "Ken Burns" effects enabled, these effects will be disabled when OpenGL is turned off.

It's essential to keep in mind that because the ProSelect Slideshow operates within a separate window, you will still need to share your entire desktop with Zoom, rather than merely sharing the ProSelect application.

We trust that this solution will help you overcome the current issue and ensure smooth interactions between ProSelect, Windows 11, Zoom, and Slideshows.

UPDATE October 2, 2023:  Windows and Mac Users

Zoom recently introduced a new Preferences setting (Zoom.us > Preferences > Share Screen (Mac) or Edit > Preferences > Share Screen (PC).  Enabling the setting “Share all Windows from an Application” will let both the ProSelect application and the Slideshow share across Zoom without sharing the complete Desktop or Screen.
