i think its about QT some other sources : https://bugs.freedesktop.org/show_bug.cgi?id=84651#c11 https://bugs.freedesktop.org/show_bug.cgi?id=84651#c5
I'm not surprised at all Drakensang worked perfectly for over a year and I played many hours, then one day it stopped. After a month of troubleshooting a workaround was finally posted, then Wine fixed something and now it works great.

I have to admit, I'm not surprised. QT5 was just implemented in a few games like Drakensang and Battle.Net It automatically broke Wine for Linux gamers. Then it took about a month for someone to create a work-around... then Wine fixed the compatibility with Wine 1.7.40 There has probably been an update by Blizzard with Qt5, but I have not seen a lot of people posting problems with it.
I am going to try to get Hearthstone running. * Prepares to jump into the deep end of the pool. Will it be a belly flop or a swan dive?
I am running the POL install script for Hearthstone. So far I could log in to my battlenet account and the game is now downloading.
The POL script works just fine. Now I can play from my Kindle fire or my Desktop. Sometimes we fail to guess what is needed for a Manuel install. If the other guy goes to the POL website he can look up the script to see what is needed or he can do like I did and use the POL script. don't forget to delete the broken install first.
All in good time I can't wait for a lot of new and older games to be ported to Linux Until then I'll be using PlayOnLinux for most of them and others will have to be obsolete in my gaming repository
