Sorry for the duplicate, but there were no options to add comments to the existing ticket for me.
I wanted to add that, I'm getting the same issue as discribed in HELP-133. Visual duplication / corruption of the UI based on cursor position. I'm experiencing this issue on multiple computers. A desktop with an Intel i7 CPU with AMD graphics card (Which had win7 and was reinstalled with win10), a second desktop with an AMD APU using win 7, and a laptop with an Intel i3 with intel based graphics on win10. I've experienced this issue for at least 8 months probably more. I've upgraded my java each time an update is made available, and every driver I know about is up to date.
Until a few days ago, I thought the issue was limited to PCGEN. Until I started trying Hexographer, which also uses java, to generate a world map. After being in that application for an hour, the same graphical glitch occurred there.
I hope this information can help narrow things somewhat.
Thank you for all the work that you do!
Windows 7 & Windows 10
