With Russia not so much. It's mostly a history of war and occupation although Poles do make a strong distinction between Russia as a country and Russians as people.
In case of other ex-WarPac countries the negativity is mostly due to communism. Although in case of Czechs a lot of pro-Russian sentiment used to exist in the past before ww1. The first Pan Slavic convention was organizeed in Prague in 1848.
In case of the Baltics there used to be a group that was very pro-Russian - the Baltic Germans were pretty much a model minority in the Russian Empire with a monstrous overrepresentation in government, military and business, during the Russian Civil War they fought for the Whites in contrast to other minorities (Jews, Georgians, Latvians etc) which formed an overrepresentation among the Bolsheviks.
Poland has been one of the spears of conquest aimed at Russia by the Popes. Just like the Knights of the Teutonic Order. So Poland's endless drang nach osten
is its own fault and not Russia's. The occupation of Poland by the Russian Empire was vastly softer than any Polish occupation of Ukraine. Russian Orthodox religion
was not rammed down the throats of Poles like the Poles tried to force Catholicism on Ukrainians. The result was the Uniates. And the reason Poland got occupied
was because it was actively engaged in trying to regime change Russia during the time of the troubles. Specifically they tried to install a fake Czar to rule as their
(and the Pope's) quisling.
The story with Poland has always been selective use of timelines. Like with the so-called partition of "Poland" by Stalin and Hitler. The fact that Stalin reclaimed the
lands that were grabbed by Poland in 1920 is selectively excluded to make it look like it was a simple land grab. Poland's annexation of western Ukraine and Belorus
was not historically based aside from delusions of imperial grandeur. Funny how one Pole told me a while back that Poland considers western Ukraine to be part of
Poland. Much like Turkey considers Kurd lands to be Turkish.
