Add an optional scissor-based clipping strategy to the GLES2 render pass, it is enabled with WLR_GLES2_SCISSOR_CLIP=1 env var. And it is disabled by default so it doesn't affect current users. On tile-based renderers like V3D (Broadcom VideoCore, used in Raspberry Pi), not using scissoring makes the GPU to render the full-surface. If scissor is applied only the tiles affected are load/render/stored reducing the GPU usage. Patch backported to wlroots 0.19 with labwc on Raspberry Pi OS with v3d running glxgear 300x300 on top left corner of screen: - Before: labwc uses 21.5% of GPU render availability. - After : labwc uses 3.3% of GPU render availability. This patch over wlroots master with sway on Raspberry Pi OS with v3d running glxgear half-screen and a terminal half screen: - Before: sway uses 23.5% of GPU render availability. - After : sway uses 13.6% of GPU render availability. |
