Subject: [PATCH] [Maxwell]: Fix shaders compilation memory leak (#2606)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

"The ObjectPool<Statement> was never being cleared after use. When compiling complex shaders, this would allocate gigabytes of memory, causing the emulator to run out of RAM and be killed by the operating system. This is a critical fix that prevents out-of-memory crashes on all operating systems when playing games with complex shaders."
