At first I thought it was an 64bit version issue as I noticed the download of the site downloaded the unstable(?) 64bit. Same issue persisted. Tried with 3.0.0 and the same blocky image and the whole computer becoming frozen.
Something to notice is that I would change from windowed to full screen at least two or three times, but the thing is that this issue has NEVER happened prior to 3.0.0. In 2.2.8 it works perfectly and it doesn't freeze the whole computer.
Since I can't even screencap or see the log, I took a screenshot of the laptop monitor. I really don't know what's happening.
