I was trying to use other versions of deck.gl. And when I used deck.gl 6.1 with property fp64, I got an interesting effect. My screen blinked and everything got worked in all browsers. Why? I compared two logs and found the only difference: \r\n```\r\n//this is from problematic logs:\r\ncontext.js:233 luma: WebGL2 context (Google Inc.,ANGLE (Intel(R) HD Graphics Direct3D11 vs_4_1 ps_4_1))\r\n```\r\n\r\n```\r\n//this is from \"good\" logs\r\ncontext.js:233 luma: WebGL2 context (Google Inc.,Google SwiftShader)\r\n```\r\n\r\nI repeated this experiment multiple times and decide that it is a root cause.\r\n\r\nSo for good case logged information is:\r\n```\r\n//logInfo(context.js:233)\r\n\r\nwebGL = \"WebGL2\"\r\ndriver = \"\"(Google Inc.,Google SwiftShader)\"\"\r\ninfo = \"{\"vendor\":\"Google Inc.\",\"renderer\":\"Google SwiftShader\",\"vendorMasked\":\"WebKit\",\"rendererMasked\":\"WebKit WebGL\",\"version\":\"WebGL 2.0 (OpenGL ES 3.0 Chromium)\",\"shadingLanguageVersion\":\"WebGL GLSL ES 3.00 (OpenGL ES GLSL ES 3.0 Chromium)\"}\"\r\n```\r\n\r\nFor bad case information is\r\n```\r\n//logInfo(context.js:233)\r\n\r\nwebGL = \"\"WebGL2\"\"\r\ndriver = \"\"(Google Inc.,ANGLE (Intel(R) HD Graphics Direct3D11 vs_4_1 ps_4_1))\"\"\r\ninfo = \"{\"vendor\":\"Google Inc.\",\"renderer\":\"ANGLE (Intel(R) HD Graphics Direct3D11 vs_4_1 ps_4_1)\",\"vendorMasked\":\"WebKit\",\"rendererMasked\":\"WebKit WebGL\",\"version\":\"WebGL 2.0 (OpenGL ES 3.0 Chromium)\",\"shadingLanguageVersion\":\"WebGL GLSL ES 3.00 (OpenGL ES GLSL ES 3.0 Chromium)\"}\"\r\n```\r\n\r\n\r\nI tried to use webgl1 (`glOptions: {webgl2: false}`), so logged information changed but result became same. There is informtion:\r\n```\r\nwebGL = \"\"WebGL1\"\"\r\ndriver = \"\"(Google Inc.,ANGLE (Intel(R) HD Graphics Direct3D11 vs_4_1 ps_4_1))\"\"\r\ninfo = \"{\"vendor\":\"Google Inc.\",\"renderer\":\"ANGLE (Intel(R) HD Graphics Direct3D11 vs_4_1 ps_4_1)\",\"vendorMasked\":\"WebKit\",\"rendererMasked\":\"WebKit WebGL\",\"version\":\"WebGL 1.0 (OpenGL ES 2.0 Chromium)\",\"shadingLanguageVersion\":\"WebGL GLSL ES 1.0 (OpenGL ES GLSL ES 1.0 Chromium)\"}\"\r\n```\r\n\r\nI reproduced this problem on all deck's examples.
