--- Comment #7 from Carlo Bramini carlo.bramix@libero.it 2013-02-08 09:38:05 CST --- Prologue: I had compiled WINE's common controls for Windows, I did it for helping my personal coding because, lot of times, tracing in COMMCTRL is useful for finding bugs. Of course, my applications are normally compiled with Microsoft's common controls, this is just a "debugging facility" actually that I use when I do not know what I must do...
Next, I must say that this bug, and also bug #27723 and bug #27724, happens also on real Windows, as you can see from the newly attached screenshot. So, corrected or not, I doubt that this defect is related to gdi32. Or, at least, not only to it.
