Unfortunately, as described on the official download page:
https://ee2.eu/patch/#information
"Linux distributions are not officially supported. Playing on them will result in graphics bugs and Out of Sync errors in Multiplayer."
It seems to affect other emulations as well. There is nothing that can be done with this problem, except switching to a supported operating system or trying a different emulation method.
Just to make clear, this is not Unofficial Patch 1.5 limitation, It's the fault of wine (or other libraries they use) that doesn't correctly translate EE2 (unpatched) procedures correctly.
