    Bitcoin Core High-DPI bug

    The text is unreadable to the point where I can't even see my balance.

    I have a 4K display, that is set to 200% scaling. Which means it's effectively behaving like a regular 1080p monitor, but it's lovely to read on as text is much cleaner.

    Does windows 10 have DPI settings like 7 did? If so, try increasing the DPI-adjustment or whatever it is named now all the way up and make sure that doesn't fix it. Qt attempts to be as friendly (camouflaged) to the host environment as possible but sometimes strange things happen with weird resolutions I have noticed.

    This problem can be reproduced under Linux by launching bitcoin-qt with QT_DEVICE_PIXEL_RATIO=2.

    Looks like a bug in the upstream Qt library. See also issue #6472.

    Qt's <=5.5 HiDPI support only works properly on MacOSX. Qt 5.6 Beta looks promising (check: http://blog.qt.io/blog/2015/12/18/qt-5-6-beta-released/).

    Thanks for the information jonas. Does this require rebuilding Bitcoin Core against QT 5.6 beta, or is there some way to have the v0.11.2 client use 5.6 beta given that it's installed? I'm just a user and not a QT or Bitcoin developer.

    @cosmicvibe: Yes. It needs a build of BitcoinQt against Qt5.6 beta. You can download Qt5.6 beta from here: https://download.qt.io/development_releases/qt/5.6/5.6.0-beta/

    @jonasschnelli Thank you, that helped a lot! This is a very late reply, but I'm pretty sure I didn't rebuild BT Core after installing QT 5.6 to get the larger text.

    Should be much better now when compiled against Qt5.6.1 (which is now our depends default QT version).

    Closing due to Qt 5.6.1 switch which addresses this (#8210).
