This article describes an issue in which RemoteApp windows disappear and the screen flickers when you switch between open windows in Windows 8.1 or Windows Server 2012 R2. A hotfix is available to fix this issue. Before you install this hotfix, see the Prerequisites section.

Symptoms

This issue occurs when an application uses WM_SETREDRAW messages to suspend active paints and is hosted as a RemoteApp.

Cause

This issue occurs because win32k.sys sets the WS_VISIBLE flag to False when the application sends the WM_SETREDRAW messages to disable paints or vice versa. However, when these applications are hosted as RemoteApps, they get hidden instead of being transparent windows.

The dates and times for these files are listed in Coordinated Universal Time (UTC). Be aware that dates and times for these files on your local computer are displayed in your local time and with your current daylight saving time bias. The dates and times may also change when you perform certain operations on the files.

Notes

  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version

    Product

    Milestone

    Service branch

    6.3.960 0.16 xxx

    Windows RT 8.1

    RTM

    GDR

    6.3.960 0.17 xxx

    Windows 8.1 and Windows Server 2012 R2

    RTM

    GDR

    6.3.960 0.18 xxx

    Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2

    RTM

    GDR

  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed in the "Additional file information" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
