--- Comment #4 from Andrew Fan andrewsuicune@gmail.com 2013-06-09 08:30:18 CDT --- I have gotten those same fix me errors from multiple Touhou games. Is the bug present on Windows? Personally, I think that this bug is related to the demo itself, not wine. Remember that since this is ZUN's first High Resolution game and since most images are being shrunken for lower resolutions, it may not be wine.
P.S. The images you posted as having the bug are not High Res. So it is natural that they blur on 960x720, which is 1.5x size for those specific images.
