Making this issue here since your multimc m1 branch doesn't seem to be able to have issues added to it; not sure if this is a LWJGL2-m1 issue or a JVM issue.
As shown in the above videos, Minecraft 1.5.2 and below have odd behavior when entering fullscreen (fullscreen only takes up 1/4th of the screen. with the empty space displaying the current skybox color), and hang when the screen size is adjusted. Furthermore, outside of fullscreen, the R and G color bytes seem to be inverted. My own tinkering with Minecraft Coder Project decomps of 1.5.2 seems to suggest that this inversion of the R and G bytes is happening as a result to something wrong with the window itself; not the OpenGL calls. This is further corroborated by seemingly only the render thread hanging, with all other threads still running. Furthermore, no OpenGL errors occur, nor a Minecraft Crash Report.
