  • The root cause identified as Windows Fall Creator Update changed time of GetPixel api call execution. Crystal Reports is using the call too many times to load images for UI. The issue affects not only Crystal Reports but some other applications, but looks like only machines with High monitor resolution. There are several developers discussions on the subject, just search for the following keywords: "GetPixel, Fall Creator Update, performance"


  • Windows Explorer process (explorer.exe) restart in Task Manager allows to start Crystal Reports normally for some cases.
  • In other cases users turned off the Exploit Protection in Windows Defender Security Center.

Developers are currently working to optimize the number of GetPixel calls CR makes.
