video demonstrating performance impact of CSS change on the scrolling and mouse stuttering in @Tuba on non-high end hardware cc @rmader @sonny
@mntmn @Tuba @rmader @sonny Oh... Did the new GSK renderer reintroduce unconditional rendering of the full shadow behind the whole window? 🙈 https://gitlab.gnome.org/GNOME/gtk/-/issues/3284
@dos We use the old GL still, due to performance regressions.
@mntmn Could you try running Tuba with GSK_RENDERER=ngl or GSK_RENDERER=vulkan?
@GeopJr @dos ohh interesting, i will try with ngl, there's no vulkan support for vivante GPUs
@mntmn @GeopJr @dos FTR., ngl requires GLES 3.0 (or GL 3.2) and etnaviv does not support that (overwriting the GL version *might* work though). So those GPUs are stuck with the old renderer either way.
