log

Guitar Pro 5 always hangs when tries to draw dashed lines (like these

core is loaded to 100% during this freeze. Sometimes it even draws odd lines
(https://imgur.com/1efGsF2.png).

This bug is regression. About 6 months ago everything was fine. It begins ~4
months ago. I don't know what causes this problem so I started wine with
WINEDEBUG=+all and tried to find where it hangs. I noticed a lot of gdi calls
which can cause this hangs. I restarted wine with WINEDEBUG=+gdi and grabbed
the log which I've attached to the bug.

I'm using Arch Linux. WINEARCH=win32.
