Hanssen --- I tested the same on a large 27" QHD 2560x1440 display and y2controlcenter didn't change to small fonts here. Looks like this behavior has to do with 4K UHD (HiDPI) 3840 x 2160 ultrabook display. -- You are receiving this mail because: You are on the CC list for the bug.

YaST needs to use QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling). It's the same as "QT_AUTO_SCREEN_SCALE_FACTOR=1 /usr/lib/yast2/bin/y2controlcenter". -- You are receiving this mail because: You are on the CC list for the bug.

Fix for the YaST control center:

https://github.com/yast/yast-control-center/pull/31

(will arrive with yast2-control-center-4.1.2)

Fix for libyui-qt:

https://github.com/libyui/libyui-qt/pull/89

(will arrive with libyui-qt-2.49.6)

I originally wrote this on Friday, but apparently never hit submit: It appears like this is unfortunately not enough - the control center uses the QPixmap API in a way that requires Qt::AA_UseHighDpiPixmaps to be set as well. That can easily be seen by running QT_FONT_DPI=192 QT_SCREEN_SCALE_FACTORS=2 su -c "/usr/lib/YaST2/bin/y2controlcenter". A much bigger issue can be found in the partitioner: All of the icons are created by using QPixmap with fixed paths, which include the resolution. This means that a 22x22 icon gets drawn on a 44x44px area on the screen, which is then obviously blurred. This needs to be done letting QIcon choose the proper file from the theme itself. I guess a separate bug report should be opened for that? -- You are receiving this mail because: You are on the CC list for the bug.
