Not sure if this is the issue however found the lines: engine "pixmap" { image { function = FLAT_BOX detail = "entry_bg" } } in geany.gtkrc lines 27 - 32 seems to be the issue on windows 10. When lines are commented out it seems to resolve the issue. Tested on ubuntu and windows 10 with genay 1.29. Is there any test that can be use to determine if this is not breaking the workaround in the comment above this code?
