Hi,
I'm using a TFlowPanel to arrange some buttons. The panel is by default translucent on MacOS (where I develop most of the time), but has a light gray background on Raspberry Pi / Linux (where I ultimately need to deploy to). This is bad because my form has a background wallpaper that is then being covered up by the empty parts of the panel. I tried all sorts of tricks already (played with Color/ParentColor, assigned empty OnPaint), but to no avail. Is this a general limitation of the Linux target or the GTK widget set or could it be caused by the older Lazarus 2.0.6 on Raspberry Pi (I use 2.2.6 on MacOS)?
Cheers
Joerg
