So nowadays, + Firefox uses Skia by default. + + However, it turns out that Skia scales really badly on remote X11 + connections. Scrolling of long web pages becomes really jolty. + + Something similar could be observed earlier already when using + Chrome or Chromium (which also has been using Skia for some time + now). + + This change in nxcomp works around those issues and greatly + improves scrolling and general browser experience on medium + throughput networks (like cable modem, ADSL, HDSPA, slow LTE). + + [1] https://en.wikipedia.org/wiki/Skia_Graphics_Engine + + Fixes ArcticaProject/nx-libs#443. + + Backported from Arctica GH 3.6.x branch. + + v2: backport to nx-libs 3.5.0.x (Mihai Moldovan) +--- + nxcomp/Loop.cpp | 4 ++-- + 1 file changed, 2 insertions(+), 2 deletions(-) + +--- a/nxcomp/Loop.cpp ++++ b/nxcomp/Loop.cpp +@@ -13017,7 +13017,7 @@ int SetLinkAdsl() + + control -> LinkMode = LINK_TYPE_ADSL; + +- control -> TokenSize = 512; ++ control -> TokenSize = 1536; + control -> TokenLimit = 24; + + control -> SplitMode = 1; +@@ -13047,7 +13047,7 @@ int SetLinkWan() + + control -> LinkMode = LINK_TYPE_WAN; + +- control -> TokenSize = 768; ++ control -> TokenSize = 1536; + control -> TokenLimit = 24; + + control -> SplitMode = 1; diff --git a/debian/patches/series b/debian/patches/series index 6a24429a4..988e11643 100644 --- a/debian/patches/series +++ b/debian/patches/series @@ -148,6 +148,7 @@ 1259_nx-X11_Make-RANDR-_set_-timestamps-follow-clien.full.patch 1260_nx-X11_xserver-Avoid-sending-uninitialized-padd.full.patch 1270_nx-X11_CVE-2017-2624-Use-timingsafe_memcmp-to-c.full.patch +1300_nxcomp_Set-TokenSize-to-1536-for-lin.full+lite.patch 9900-dxpc-license-history.full+lite.patch 0016_nx-X11_install-location.debian.patch 0102_xserver-xext_set-securitypolicy-path.debian.patch |
