Flicker when activating a control

Hi Corie,

Due to the nature of how .NET Controls work when adding/removing them there might be a little bit of flicker. We try to suspend layout of controls during the add/remove process though to keep any flicker to a minimum. If you think there is a major flicker though, please let us know how to duplicate it in our sample project or email us a project of your own and we can take a look to see if we can do anything more.

I see this bug too. This is reproducible with the sample project. Here are the steps:

1) Run the "Bar Controls" sample.
2) There is BarManager Properties window to the right. Hit its pin button to make it hide.
3) Make it auto-show and hit the pin button again. There is large solid rectangle displayed for a fraction of a second in the left top corner of the application.

Thanks,
Ernst

Just spent an hour on this one... we have our code set up properly by suspending the layout of the parent control, adding the tool window container, and then resuming layout. However it seems to be a bug in Windows Forms where it will briefly draw the added control's background and then instantly draw it where it should.

Our originaly code should work fine and I tried manipulating the order of everything, but nothing seemed to resolve it. I finally did come up with a workaround of making the container being added a zero-size and then resuming layout, and then setting its real size. That does seem to work around the Windows Forms bug.

It will be in the next maintenance release.
