[Mono-winforms-list] Blank windows

[Natalia Portillo]

No, I have my own framework for translation.

However it only changes the button images, the forms background image and
transparency key are constant, defined as so:
           this.BackgroundImage =
global::OpenMetaverse.Properties.Resources.frmAbout;
            this.TransparencyKey = System.Drawing.Color.Yellow;

Once the "blank window" bug appeared it doesn't work until restarting the
whole machine.
Even then, if I've put a conditional "if running on mono don't set that
parameters" the windows still appear blank.

Tested on following environments:
Mac OS X 10.6 (64-bit kernel), Mono 2.4.2.3
Mac OS X 10.6 (64-bit kernel), Mono 2.4.3
Mac OS X 10.6 (64-bit kernel), Mono 2.6 RC 1
Gentoo Linux x86-64 + KDE4 (composite enabled and working), Mono 2.4.3
OpenSuSE 11.2 (fresh install on virtual machine) x86, Mono 2.4.2.3
Mac OS X 10.5 (PowerPC G4), Mono 2.4.3

I don't know if buttons may also be causing the problem, they are PNG with
alpha channel loaded from embedded resources.

I suppose I can prepare in the day a test project for filling a bug.
