Well after a bit of googling found this:

Empty Screen Launching Chromium-Browser Over X11 from Ubuntu 16 to OSX XQuartz

On MAC Quit Wappler completely from the tray, right click quit; Start the Terminal and type: open -a "Wappler.app" --args --disable-gpu On Windows Quit Wappler completely from the tray, right click quit; Right click your Wappler shortcut on the desktop/start menu and in the Target field, after the Wappler exe path add: …

Thanks, I’m tryed to insert the parameter in package.json “chromium-args” but it doesn’t work the system shows white screen in Wappler.

Hello, to solve problem I inserted the parameter in wappler.desktop file like bellow :

Exec=/usr/share/wappler/Wappler -tray --disable-gpu

[George]

Try Wappler 4 beta
