--- Comment #1 from Damjan Jovanovic damjan.jov@gmail.com --- To minimize it to the system tray, you have to go Options -> Preferences, and under Environment -> Window, tick "Minimize main window to taskbar status area (system tray)".
However whether I do this or not, I cannot reproduce the problem. The column headers are always drawn, whether I use 5.17.3 or 5.17.6, whether I scroll down or not, whether the left or right pane is selected or I've only got a single pane, whether I am using compositing or not, whether (in winecfg) I allow window manager to decorate/control windows or not.
Please start from a clean WINEPREFIX and change settings one at a time until you find which single setting causes the headers to not get drawn.
