Review request for Plasma, Kai Uwe Broulik, David Edmundson, and Vishesh Handa. Bugs: 337712 and 338308 http://bugs.kde.org/show_bug.cgi?id=337712 http://bugs.kde.org/show_bug.cgi?id=338308 Repository: plasma-framework Description ------- Use font metrics to scale icons for high dpi outputs QScreen, through EDID reports bogus values for physicalDotsPerInch*(). This leads to oversized icons on monitors with bogus edid information. This patch changes the ratio underlying to the icon sizing for displays with a DPI > 96 * 1.5 to use the ratio between the font as rendered (its effective pixelSize, essentially) to scale the icon sizes up. As we rely on proper font metrics throughout already, this should bring sizing in line with the font, which is something that makes sense as it means we're sharing the underlying mechanism (font metrics) for sizing in different areas. The downside of this patch is that we're essentially working around an issue that should be fixed in the hardware, the monitor's edid. Unrealistic. print dpi / sizing in dpitest Print out some useful information to deduce dpi and pixel sizing. David, and Kai Uwe, Vishesh (since I know you have a high DPI displays), could you run this patch for a bit and check if it works for you, too? I've pushed it to plasma-framework[sebas/dpi] for your git convenience.
