Glitches On Every Control


Hi, I’m starting my evaluation today and facing this issue.

What I’m used

  • Visual Studio 2017 (latest update)
  • Windows 7 SP1 64 bit
  • Internet Explorer 11
  • Wisej 2.0.13 (fresh installation)

First I create a new Web Page project, it brings me into the designer tab. However, I see black panel on every control I add to the page: It seems works fine on Google Chrome:

What I’ve already tried

  • Restarting VS in admin mode
  • Restarting my PC
  • Reinstall Wisej
  • Changing VS theme
  • Changing target .NET Framework
  • Changing Windows appearance (enable/disable aero, transparent glass, etc..)
  • Changing preview theme..

Problem is Windows 7 is end of life, hence IE may not have updated to the latest version.

Hope this helps

    Does it means that Wisej can’t run correctly on Windows 7 machine?

    The problem is IE in Windows 7 used by the designer. Wisej doesn’t care about which OS you run for the client as long as the browser supports HTML5. For development Windows 7 is probably a bit old. Are you using Visual Studio Community Edition? I have seen a similar problem on newer machines with VS Community and it was related to Windows permissions.
