I'm Galaxy_2Alex from the Minecraft community and I've recently discovered a graphical glitch with certain graphics cards from the AMD Radeon HD 2xxx, 3xxx and 4xxx, more specific the IGP ones (List). I have two reports, one from someone with an Radeon HD 4200 one one with Radeon HD 4250 (so it might only affect certain 4k cards), both have the so-called "Invisible world" bug (like this: http://imgur.com/a/206qB#0), which is NOT caused by the Beta drivers (because the Beta drivers are not available for these cards as far as I know), the drivers are the latest for these cards (13.9). This also only affects the newest development versions of the game, the full release works fine(More information on the whole topic + some test results from other cards: http://www.reddit.com/r/Minecraft/comments/1ygdx4/bug_tracker_team_needs_your_help_to_check_on_a/)
...no, this can not be fixed by Mojang. I talked to MogMiner, who is responsible for the rendering in the game, and he said that it's basically AMD's side that is not working correctly. So, I have some questions...
1. Is there any kind of report service for reporting such bugs? Because these cards are only 4 1/2 years old and should still be supported, and as far as I can tell, alot of people will be affected.
2. Does reporting it even make any sense? Because I'm certainly sure that AMD is not going to do anything about it, as their OpenGL support is, as far as I heard, very poorly done. But, as stated, this would affect a lot of people.
Thank you for answering in advance, let's hope we can solve this issue. Any information needed will be provided as soon as possible.
