I recently use QGIS 3.0.0, in Windows 8. Today, I work with symbol. When I use SVG symbol, the symbol selector window become so long, even under the taskbar, I cannot resize or drag up the window (it won't allow me). No, it's not just covered by taskbar, it's under the monitor boundary.
Previously I used QGIS 2.18 .12 and never met this problem.
Maybe this is just silly question, but I need help.
