Package: x2goclient Version: 4.1.2.2 (Qt-4.8.7) When using Matlab on an Ubuntu linux server accessed through x2goclient, the Matlab window has inverted colors (e.g., background is black, text is various colors with different highlighted colors). I'm using x2go from a 2017 Macbook Pro with MacOS Catalina. I've recently found the matlab window inverts its colors when the x2goclient window is off-screen to the left, but when it's completely contained by my monitor window or slightly off-screen to the right, then the colors are normal. A similar problem happens on my colleague's 2020 Macbook Pro with MacOS Big Sur, but no matter how he configures the x2goclient window, his matlab screen still has inverted colors.
