Backtrace of the crash (Tropico with Wine 1.3.16)
When switching to (or starting a game when the last setting was) the hardware
accelerated mode in Tropico, the game immediately crashes with the attached
backtrace.
Please note, that I wasn't able to attach an GDB to Wine/Tropic, if I do, I get
tons of SIGSEGVs in Tropico before I get anywhere close to this bug. So I fear
the Wine-generated backtrace must do. If you need further information, beyond
the following, please let me know.
DDX: 6.14.0
X.org: 1.9.4.901 (1.9.5 RC 1)
Kernel: 2.6.38
libdrm2: 2.4.24
Mesa: 7.10
The "Severity" was set in accordance with
<https://bugs.freedesktop.org/page.cgi?id=fields.html#bug_severity> where a
crash is named as critical.

Wine sometimes does FBO blits directly to the front buffer. This currently tends to crash due to the front buffer surface not being created yet. The attached patch should help with the crash, but it may not be enough to make the actual blit work correctly. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread

Tropico works perfectly now with hardware 3D acceleration enabled (though it's a little bit slow). -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
