I use MS Desktops (here) on 64-bit Windows 7 and find that when Atom is running, when I bring other programs to the front, they don’t always refresh completely, and I have to click again in the window or scroll the window to force a full refresh.
This seems to be a particular problem when using a desktop other than the default one, and when the programs are not running full-screen. I’ve had particular problems with the UI not updating in the Arduino IDE, but VS2010 and others also suffer from this.
The screenshot shows empty files in Atom and the Arduino UI. Atom was on top, then I clicked in the edit area in the Arduino IDE to bring it to the front and it drew as shown.
Any advice would be welcome!
