Hi folks. I'm an old user of Real Basic since the beginning. Been out of it for a while but have come on board with Xojo. Running the latest 2019 ver. 3.1 on a iMac with Sierra and a bootable SSD with Linux Mint 19.3. Xojo works great on the Mac, but some curious issues in Linux. For one, the window backdrop refuses to display the image in the IDE. Running the app in debugger does show the image, but for layout purposes it's unacceptable. Hoping for suggestions. Thanks.
