Summary: Pausing Minecraft and Minimizing the window will cause the console to constantly write the following:
[Client thread/ERROR]: ########## GL ERROR ########## [Client thread/ERROR]: @ Post render [Client thread/ERROR]: 1286: Invalid framebuffer operation
I've been experiencing this since 15w51b, if Minecraft is lagging too, this will come up:
[Client thread/ERROR]: ########## GL ERROR ########## [Client thread/ERROR]: @ Post render [Client thread/ERROR]: 1286: Invalid framebuffer operation [Client thread/WARN]: Something's taking too long! 'root.gameRenderer.level.terrain.render_Solid' took aprox 449.770913 ms [Client thread/WARN]: Something's taking too long! 'root.gameRenderer.level.terrain' took aprox 461.483944 ms [Client thread/WARN]: Something's taking too long! 'root.gameRenderer.level' took aprox 474.739275 ms [Client thread/WARN]: Something's taking too long! 'root.gameRenderer' took aprox 506.825792 ms [Client thread/WARN]: Something's taking too long! 'root' took aprox 508.339349 ms
The type of lag doesn't necessarily have to be a level.terrain, but you get the general idea.
To Reproduce:
1. Open a Minecraft World.
2. Pause Minecraft.
3. Minimize the window.
Notes:
1. Based on testing & reproducing this issue, this may not happen on some machines, OS's or Java versions.
2. Game outputs are attached files, these are two instances of it happening.
