Mame - random black screen at launch

[Nosfé]

Hello,

As title says, I have a black screen randomly when I launch a mame game.
Sound is OK, but video is not working.

I have found that mame is running, but not "on focus", I can have video back by using "alt + tab" on my keyboard.

I running attract mode on windows 10 64b.

My cfg file :

Code: [Select]

executable           C:\Emulators\mame0209b_64bit\mame64.exe
args                 "[romfilename]" -skip_gameinfo
rompath              C:/Roms/MAME/
romext               .zip;.7z

I have an other issue when i try to launch mame core on retroarch (with attract mode), games launch one time, then when I go back to mainmenu, I can't launch games anymore, and have to launch retroarch without attract mode to launch game.
No issue with other retroarch core (psx, snes, n64, etc...)

I'l like to fix one of these issue to get my bartop fully working

Thank you for your help
