--- Comment #9 from Joerg Schiermeier mywine@schiermeier-it.de --- (In reply to schnedan from comment #5)
Wine 8.19 has arrived in my distribution and I want to report, things are worse now.
Which version of TreeComp do you use? Version 4.0b52 isn't the recent one. Could you please use the latest version v 4.0 b62 and check again?
Graphic issues still persist and treecomp throws exceptions very fast. From once a day or so I now can reproduce it by starting a first sync run...
Also: Did you try to run TreeComp with wine's Windows version set to "Windows 8" or below (e.g. "Windows XP"). Please report if something changes if you do so.
