--- Comment #6 from sebastianhatt@gmail.com --- UPDATE: -the latest winehq-devel 1.9.0 also has the bug (this time I carefully followed the instructions on http://wiki.winehq.org/Bugs, installed the latest development version of wine (without PlayOnLinux), made a clean wine prefix, reinstalled Sibelius. Same result. -wine 1.4, wine 1.5 and wine 1.5.10 do NOT have the bug. -wine 1.5.11 and wine 1.5.12 do NOT have the bug, but have other problems specific to those versions -wine 1.5.13 introduces the bug!
For now I will stick to 1.5.10. However, Sibelius 6 runs much slower on older wine versions than on 1.9.0 and other recent versions.
Wine 1.5.13 changelist lists among others the following changes: - Client-side window rendering using the DIB engine. - Support for transparent window areas using color keying. (https://www.winehq.org/announce/1.5.13) Specifically, Alexandre Julliard has made lost of changes to user32 and gdi32 (graphics/window handling) that are possible culprits.
Both could have something to do with this bug.
What do I do from here? I'm a wine newb. Do I have to use git bisect? It looks complicated. Any help?
