    Description

      I'm trying to get QImages to show up in the debugger. I'd like to do to this on Windows, but I read that it's not supported for CDB, so I'm trying with GDB on Ubuntu.

      While debugging, I right click on a variable in the Locals and Expressions pane and select Change Value Display Form > Change Display for Type "QImage" > Normal (as mentioned here). The UI seems to do something for a split second, but nothing changes in the Locals and Expressions window. If I then go back and check the value that I selected, I can see that it's gone back to "Automatic".

      The same thing happens with the other display options.

      I've attached a debugger log that was saved just after changing the display type to "Normal".
