Unfair Punishments and Client Problems

I had recently crashed from a ranked game, all I did was try to switch from borderless to windowed because every time the game loads up in borderless the screen only appears on the top left side of my screen, when i switch to windows and back, it will be working perfectly again. Full screen is useless for me because the screen is always glitched and whenever I try to alt-tab it crashes with a bug splat and I have to restart my computer. So I crashed again today, and I thought it was fine, because i was used to the occasional bug splats and stuff. But what was not okay was the punishment for it, I left a game for the first time in months and I got low priority queue for 5 games on 20 minutes, Riot please, do fix your client or at least make the punishing system a bit fairer, it is extremely aggravating to see it happen for no reason.
