STEMWin.GUI_MULTIBUF_Begin flickering

After including some time critical realtime process to the mcu application which also handels a display flickering occurs. (bad idea i know)

I found that the flickering occurs when the GUI_MultiBuf_Begin function is called.I never implemented a double buffer but thinking a bit deeper into it, it's a legible question if it's really necessarry for this function to do something which causes flickering...I made an experiment where the GUI_MultiBuf_Begin runs through without getting interrupted by the realtime process and the flickering is nearly gone.Maybe would be a legible question to segger what the heck they are doing in this func to cause flickering.Any ideas?

Hi,

thanks a lot for your effort. I wasn't aware segger is also in charge for the stm32-giveaway-version of the library.
