+When O2 level is enabled raspi3b board crash randomly when creating abuffer of a differnt size
+Description of problem:
+Sometimes when running the code creating a framebuffer different from the default size ej:1024x768 qemu hangs and crash with a SIGV, making a weird screen that's painted with the original size and the background of the current window merged onto a large window. This happens when you resize a window without updating it's contents, so qemu is crashing before the first frame after reising the window.
+Steps to reproduce:
+1. Create a producedure similar to the one descrived below
+2. Run qemu with O2 enabled(debuggind disabled)
+3. You may need to run it multiple times to see the bug(like two or three times)
+Additional information:
+Here is the example procedure implemented on rust, the mailbox interface is test and it's sure that the procedure it's well implemented:
