When running CfdOF these days I have found a harmless graphical glitch that may or may not be a bug:
When running a second simulation straight over a first one, the graphs of residual show the following:
As you can see, the icons and part of the graph background are repeated. The repeated icons are non-functional. The current icons are.
Note: I'm using the new ProDark theme (see ProDark theme in UI/UX section of the forum) but the bug also occurs without the stylesheet active.
