QWidget - Multi Monitor - Single Desktop - X_CopyArea Bug under Ubuntu



  • I can't figure out what's going on with this Bug i got:

    bq. X Error: BadMatch (invalid parameter attributes) 8
    Major opcode: 62 (X_CopyArea)
    Resource id: 0x4e00004

    I wanted to display two widgets on two Monitors with one Application.
    I configured my Target with the following screen Configuration (Single Desktop, Multiple Monitors):
    "Screenshot":https://drive.google.com/file/d/0B-hV1PD2owcHUHVNV1ZVTjV4WWs/edit?usp=sharing

    Weird is the fact that it works for an old X-Server under Suse. Under Ubuntu it doesn't.

    Btw:
    I must use this config (there must be no virtual Desktop on two screens), and i just want to get why it doesn't work.

    • Same dirver
