I know Xara was developed using some clever tricks and shortcutting the GUI that MS defines for use under Windows. It's the reason this program is so blazingly fast and fluid while working with huge bitmaps and drawings.

But .... it also has some drawbacks. For instance, when I want to share the window with MS Teams the screen start to flicker.
Has anyone experienced this behaviour also?

If not, then I can blame my graphics driver software (Nvidia) or else it's a serious issue which needs a workaround (I found one: export to PDF and share that file but then you're not able to edit while presenting...)
