[Lazarus] Grey windows in Lazarus IDE with GTK2 in Mint 17 + KDE

[Juha Manninen]

I suspect this is yet another GTK2 version related bug. Has anybody seen it?

When opening a modal window like the About box, other windows turn
grey because they are
disabled. That is OK.
After closing the modal window they still remain grey although they work OK.
Only minimizing and then restoring the IDE helps bring the normal color back.

This is the latest Linux Mint 17 with KDE desktop.
