As a Romanian national in Regency Hungary, Vida was under continuous supervision. His studying at the Hungarian School of Fine Arts was interrupted by stints in a labor battalion, though he managed to escape during the Siege of Budapest. He rejoined the Romanian Army and, by the end of World War II, was stationed in Skalica. Returning to Baia Mare, in his thirties he emerged as a favorite artist of Romania's communist regime and became a deputy in the Great National Assembly, but voiced criticism of the regime's artistic standards. He repeatedly tried to resist the rise of Socialism Realism, and depicted Expressionism as a more authentically revolutionary current.
