Root Cause

A defect in Pegasystems’ code or rules

In Pega 7.4, the 'What’s new' widget uses WebGL for the animation. If you are using Citrix or Chrome with hardware acceleration disabled, WebGL rendering is negatively affected, leading to slow performance. In addition, WebGL can have a major negative effect on your browser (Chrome or other browser).

See the Pega 7.4 release note, https://pdn.pega.com/release-note/browser-unresponsive-when-logging-designer-studio. 

Resolution

To avoid this issue in Pega 7.4 Designer Studio, when the 'What's new' widget displays, click the button labeled 'Hide this until next release' .
