Hello Esa, you were the last upstream contact for ace-of-penguins hence I would like to forward a Debian bug report to you. I can confirm that ace-freecell cannot be started on KDE desktops. The error message is:
X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 73 (X_GetImage) Serial number of failed request: 25 Current serial number in output stream: 25 Interestingly the other games work and when I run one of them first and then try to start ace-freecell, the game works without any issues as well. So there might be some missing initialization in ace-freecell which the other games do correctly or maybe it is something completely different. I can reproduce this behavior only on KDE, so it might also be some kind of KDE bug. Do you have any ideas how this issue can be fixed? Regards, Markus
