We don't support Android. Let us know if the issue reproduces on Linux though.

So I just tested again, I think 3dnow disabling might have fix this? If you could retest with main fex and wine would be great

I have retested with latest FEX and still reproduced it. Looks like it doesn't related to 3dnow, it's more like the position calculating error.

when the black screen occurred, the vegetable tips will move from right place to left bottom. when the blue screen occurred, we can imagine it the map is outside of the screen? and if i move a little bit on the blue screen, i can't enter the level again.

and i tested your latest wine and found the latest thread suspend patch may cause gamepad missed some event (wine_hid_update thread long sleep and makes gamepad uncontrollable) on high loading game and a low probability random crash occurred with exception 0x0 when program started.

Any logs i needed to provide?

I fixed the gamepad issue earlier today when did you pull to confirm? What fex settings are you using, since I can't repro as is

UPDATE: Gamepad issue fixed and previous exception 0 crash also fixed. but the latest "wineserver free map area patch" still caused some invalid addr crash when starting game on steam, fallback to previous hack patch works fine.

@bylaws after picked your new patches, issue looks fixed!

Was this a bug in 3dnow emulation?

If my wine side changes fixes this then I've no clue what the bug remotely was ahah, probably some weird garbage collection issue

UPDATE: the black screen looks fixed, but the blue screen issue still exists and fixed after i enabled FEX_X87REDUCEDPRECISION option

so it maybe a calculation issue, this issue may still needs to reopen i think.

I am trying to reproduce this with a recent FEX. I cannot see any blue screen. What's your .fex-emu/Config.json? Also, do you still see a blue screen with FEX_X87REDUCEDPRECISION=0?
