Vulkan: Discard scissored clears where scissor is null If a clear becomes a no-op because the scissor has a width and height of 0, return early and skip the draw. This also works around a driver issue on some devices where it was ignoring a null scissor and drawing the clear anyway. Found with deqp test: adb shell am start -n com.drawelements.deqp/android.app.NativeActivity \ -e cmdLine '"deqp --deqp-case=dEQP-GLES2.functional.color_clear.* \ --deqp-log-filename=/sdcard/dEQP-Log.qpa"' run_angle_end2end_tests --gtest_filter=ClearTest.EmptyScissor/ES2_VULKAN Bug: angleproject:3114 Change-Id: I6cf2716bd93bb332f74b44c7250e363c68cc614f Reviewed-on: https://chromium-review.googlesource.com/c/1436841 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org>
