I tried the 64bit Linux version on Ubuntu 14.x...
The Linux machine is a virtual machine running on Hyper-V. It does not have graphics hardware acceleration, but it has two CPU cores and 4GB of RAM assigned, which should be enough (on the host are way more resources available). I connect via RDP to the machine (installed xRDP and XFCE to get this working). I am able to run Spriter; I can create a new project from a directory... all sprites are properly loaded. The frame window appears white right from the beginning; the vertical and horizontal lines that illustrate the center of the view are not visible. When I drag a sprite into the frame window, the sprite does not show up... the entire display of the window seems to be broken.
Any suggestions?
