And yes, I do consider scene stealing and derailing to be potentially damaging to other people's fun. I've seen it ruin scenes and plots ("I solve the whole thing immediately, by myself!"), and the people involved in the worst cases didn't seem to care because "it's what my character would have done lol." (I have several "wonderful" stories of what not to do, in fact, but those are probably better suited for the Hog Pit.)
On the 'I solve the whole thing immediately front', I agree and disagree, and as we just had a big whole Lets Talk About Plots on M1963 tonight, and we talked about just this thing, I have various thoughts.
First, those people with an urge to solve everything in everything they do -- they are robbing everyone else of fun. This is bad.
Second, however, is that sometimes a player might come up with a clever approach using their niche powers that really do solve a scene all by themselves. This is good. To not let them shine in this way, to not reward their cleverness and specialty, is to put plots on a rail and that is bad.
Third, if someone tries to solve everything there is very often a likely consequence you can or maybe should apply. Rarely, I think, is a scene constructed where someone can really win it individually without going all out on such a way there might not be collateral damage at worst or unnamed consequences at best. These should be applied by the GM carefully: you shouldn't punish players for cleverness, you shouldn't wield consequence as a punitive measure because your plan got derailed. Your problem here was having a rail at all.
Finally, its very, very important to let each and everyone who can reasonably do so -- shine in their moment. Note the first -- if the character is playing like they solve everything ever that's another matter. But if you have your iconic moment of awesome, the GM shouldn't hold to a rigid set of reality that punishes you for it unless you went a bit crazy. Let the player shine.
This is all a little off topic but, hey, you know, it happens.
All of this can be boiled down to: Collaborate. This is a collaborative environment where we all want to have fun.
But accept sometimes the unexpected happens and that's a good thing.
