Created attachment 1794 image that flickers I have an image that flickers inside the viewer. It is not the images problem, in fact the flickering appears with a specific geometry of the ristretto main window. I get ristretto to flicker with the attached image and the next values: LastWindowWidth=636 LastWindowHeight=656 The image has a size of 1860x1470. I'm pretty sure that given the theme I'm using and the font size that is set in my appearance preferences, it can have no effect at your side. I had like to tell you with which size of the picture viewer ristretto starts to flicker, so the size of the picture viewer zone is 636x502.
