hwacc build crashes on direct scanout.

[Bram Stolk]

This pertains to the HWACC branches of the chromium snap.

When launched full-screen on an Intel iGPU, the hardware overlay use will result in a core dump.

This could be related to direct-scanout and overlay planes?

To reproduce:

$ chromium --start-fullscreen

OS: Ubuntu 22.10

Chromium: 111.0.5563.19-hwacc

GPU: Alderlake iGPU

Unfortunately, removing the --enable-hardware-overlays flag does not help.

Still crashes when full screen:

Does not crash when using AMD gpu, instead of Alderlake iGPU.
