Minecraft Forums

Hello im new on the forums because I have an issue I need solved. I have not been able to play minecraft for 3 months because of "a flickering launcher" or something like that. Basically every time I load minecraft and play Single or multiplayer, the window minecraft is in Flickers, in a way where I cant type in a server IP or im walking and the keyboard has a mind of it's own. (im pressing D to go right and it pushes me that way until I press D again.) I currently have a modded client w/ Forge modloader and I only have a few mods.

Now I cant play w/ my game constantly doing this, and sometimes it crashes. This is the report I got last:
