Created attachment 112763 [details] screenshot On HiDPI screens the logout screen has distorted fonts & graphics. It seems like bitmap scaling is applied instead of rendering the content with a higher dpi setting. This causes especially text to appear distorted, as subpixel smoothing causes further colorful artifacts.
follow up: for the screenshot I had graycsale anitaliasing enabled for text, so it doesn't look asugly as it would with subpixel/rgb antialiasing enabled.
