Trying to play D2 LoD and I continuously get a flickering screen.

Any help in the resolution would be appreciated.

I have the same problem here. I am using the 4.0.16 version of POM and xQuartz 2.7.1 .
When I launch Diablo 2, the game is flickering. Then I press Cmd + Alt + A two times and I get Diablo 2 in fullscreen with correct graphics and the game runs flawlessly, but the game isn't in fullscreen anymore

Try to use wine 1.2.3

I tried wine 1.2.3 and in the WINE configuration (access by the Wine tab of the game in POM), I disabled all the options of "Window Settings". The game runs now flawlessly.
Thanks a lot Quentin ;)

Can you explain what you mean by this?

thanks for this guys fixed my problem but now that i can see D2LOD. I'm trying to patch it and it says please make sure Diablo2 is closed for the patching. How can i close D2 within x11 to patch d2 or how can I manually patch the game.
