    Default QT designer hangs windows remote desktop session

    Hello,

    I use QT designer 4.8.7 on windows server 2012 standard using remote desktop session. If I do the following steps:
    1) start QT designer
    2) Create a main form
    3) On the main form, drop a pushbutton, and resize it to make it very big
    4) try to move the button with the mouse.

    Then the RDP session starts to hang at step 3), or 4). If I disconnect the session and reconnect again, the hang is solved, but trying step 3 and/or 4 hangs the session again.

    I think it has something to do with the ability of windows to show transparent windows over a RDP session. I tried many things but no solution yet.

    Has somebody has a workaround for this?

    Best regards
    Carl.

    Default Re: QT designer hangs windows remote desktop session

    I confirm this issue.

    We run;
    - Server side;
    - PyQt4-4.11.3-gpl-Py2.7-Qt4.8.6-x32
    - Windows Server 2012 R2 Standaard
    - Client side;
    - Windows 7 Professional
    - image.png

    I also note that when I drag a small enough (so preventing the issue) button in the RDP session it is invisible. When I drop the button it becomes visible.
    When I do this client side the button remains visible while dragging.
