fullscreen problem

[YoshiManden]

so GM's i know you get alot of these but its not like one ive found on the discussion page because this time i was playing in windows mode normally and it was a bit smaller than usual so i wanted to enlarge it so i put it in fullscreen mode while i was in the server itself and the screen goes black but everything is running fine its just the screen i mean i tried taunting and i heard the sound and whent i shift+tab its still black but then i can press the windows key. (my point is i cant exit the game because i cant see and the alt+f4 command dont work)

Alt-F4 should always work as long as you don't have the steam overlay opened.
If full-screen mode isn't working for you then try using "window borderless" mode, visually it's the same but there's a difference with how it's handled by the OS.
If you have switchable graphics then make sure LaTale is set to always use your high-power GPU.
Try running the game with the steam overlay disabled. (right-click the game in your steam library, click properties, un-tick "enable the steam overlay while in-game") and see if full-screen mode works then.
