Created attachment 425112 [details] Image of bug occurred on youtube and output from webkit://gpu Hello everyone, i'm having some issues when i'm trying to use epiphany on my linux system, i already open an issue on them gitlab, but they tell me that this bug its from webkitGTK, so, here i'm... Problem: When i enter some heavy sites, like youtube or reddit, the performance drop alot and the screens start to blink in red,(sometimes stay red around 10s). My system/ WebkitGTK info are on the attachment section, there you will encounter the output of "webkit://gpu". i've already tried "WEBKIT_DISABLE_COMPOSITING_MODE=1", this only change the color of bug, from red to black and the performance drop as well. for those who don't want to download the info, here are some of i judge as important: Operating system Linux 5.11.11-arch1-1 #1 SMP PREEMPT Tue, 30 Mar 2021 14:10:17 +0000 x86_64 GTK version 3.24.27 (build) 3.24.28 (runtime) GStreamer version 1.18.4 (build) GStreamer 1.18.4 (runtime) WebKit version WebKitGTK 2.32.0 (tarball) GL_RENDERER GeForce GTX 650 Ti/PCIe/SSE2 GL_VERSION 3.2.0 NVIDIA 460.67 (I already test some old drivers and the bugs still appearing) GL_SHADING_LANGUAGE_VERSION 1.50 NVIDIA via Cg compiler GLX_VERSION 1.4 API OpenGL Type X11 Screen geometry 0,0 2560x1080
