Product: PokerStars desktop client
Symptoms: Using Intel drivers starting from version 27.xxx..., open client and open 2 or more poker tables (there is no leak when only one table is open) in observe mode (you do not need account to observe games). In task manager observe how PokerStars process consumes memory at about 2Mb per second.
This does not happen with 26.x versions or any other GPU (Nvidia, AMD)
Cause: We are confident that driver causes memory leak when using glBindBuffer function (to unbind buffer). It seems that when using multiple OpenGL contexts driver confused and does not deallocate buffers (one window does not produce memory leak).
Configuration: there is no specific configuration which causes this problem, we used different laptops and desktops to verify the issue and in all cases downgrading drivers to 26.x would fix the memory leak.
Impact: application becomes unusable after 10-15 minutes (crash caused my out of memory error)
