Version: 2.3.2 (using KDE 1.2) OS: Linux When konsole background is set to black and it's maximized or made full screen it first paints white or gray then gets black. Doing this on a big screen is hurting eyes. Reproducible: Always Steps to Reproduce: Minimize and then maximize konsole when background is set to black. Actual Results: Konsole is first white or light-grey then black. Expected Results: Instant black background with no flashing.
Try starting Konsole with "konsole --notransparency". Some video drivers have issues with ARGB windows.
It still happens. When computer is overloaded it's easy to spot drawing of konsole. First it has a light background before the main widget appears and then black window with text. Try to open 2x fullscreen konsole and then switch between them with i.e. alt+tab quickly. You should be able to see white flashes. best Wojtek
