long time no see, it's me again. work has kept me busy, but I'm back for a bit.

I have the game working fine with a small wine hack, and I am working with GGG to (hopefully) have it fixed on the game side so that everyone will not have to use patched wine in order to play.

depending on the time taken to resolve this either I will post the patch in a day or two or there will be a game patch which resolves it. please be patient!

having spoken with GGG, I feel confident that an upcoming game patch will fix this issue.

the problem is caused by PoE attempting to call SetPixelFormat() on the root window during device initialization in its startup, and it is the same as this bug. since the error detection written by GGG is superior to that of the game in the bug, a simple error dialog shows up instead of a crash.

for those of you bold enough to try, the hack linked through that bug can be modified slightly to work with current versions of WINE.

Well it works, if you compile wine yourself.

However, due to the nature of wine (install and uninstall) i'd suggest to wait until poe patch comes.

wineHQ says they will fix the problem after 1.4 is officially released, which should be March-April.

Now to patch it manually, you need the source code of wine. Then edit "/dlls/winex11.drv/opengl.c".
You'll find the relevant bits of code around line 1633.

Where you need to change in this 'if statemet':
"
if(get_glxdrawable(physDev) == root_window)
{
ERR("Invalid operation on root_window\n");
return FALSE;"
}
"
to this:

"
if(get_glxdrawable(physDev) == root_window)
{
physDev->current_pf = iPixelFormat;
FIXME("cannot set pixel format on root window\n");
return TRUE;
}
"

and then save the file and install wine.


PS. I tried this on 1.4 rc2 source, but it should work on stable 1.3 as well.

PPS. My ubuntu laptop does not have good graphic card, therefore i got only 10fps and that is not enough to play. So i do not know if there are any other problems with the PoE on wine.
