what you are trying to do exactly? Move the mouse inside the different d20Pro application windows what the result was and/or what steps you took? Moving the over buttons causes strange graphical fragmenting and refresh issues to appear starting from the mouse's current position. Is the issue repeatable? Very, very repeatable what OS you are using? Windows 10 what rules system are you using? Pathfinder what version of the software are you using? 3.7.3 I don't know what caused this strange behavior to start, but it may have been after my last java update. After I've had d20Pro open for more than a few minutes, extremely graphical refresh problems start to occur. I will see things as shown in the attached file "Screen Glitch", and even on the launcher window, as shown in attached file "Screen Glitch 2". My Nvidia graphics card drivers are up to date: GeForce GTX 1080, vers. 399.07. I'm running DirectX runtime vers 12.0, on Windows 10 Pro, 64-bit. There are no errors thrown, but I've attached my d20Pro.log regardless. Current display settings are 2560 x 1440, but it also happens on 2048x1080. Refresh rate is 60 Hz. Please help, it makes the application almost unusable.
