I tested it with linux 3.19 and different (git~51b43c5, 10.4.6, 10.3.5) mesa versions, but they don't seem to make a difference. So, no, a338dc01866ce50bf7555ee8dc08491c7f63b585 does not help. Even with mesa 10.3.5, where some people reported this was the the last working version for them, the hangs occured. So it's probably related to some kernel issue, too. The hangs only seem to occur ( at least surface ) on Minecraft 1.8+. Probably because that was a bigger update and they changed the rendering code significantly. The hangs occur every few seconds and freeze the screen for <5s. Unfortunately I get a similiar issue with FTB/modded Minecraft 1.7. But this time the game itself runs fine, but whenever I switch the virtual workspace in my window manager (awesomewm), it takes up to several *minutes* until the system reacts again and the screen is updated. This only happens if the game was running for some time -> probably more vram/gtt usage. Even the cursor freezes. Big annoyance. The testing was done on a HD5850, so r600g is affected, too.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
