I cannot reproduce this on STP 151 on macOS Ventura beta. Created attachment 461769 [details] Video Recording - Flashing - macOS 12.5.1 (In reply to Alexey Proskuryakov from comment #1) > I cannot reproduce this on STP 151 on macOS Ventura beta. I just captured a video to showcase issue using STP 151. Created attachment 461787 [details] network fetches I can NOT reproduce on Safari Version 16.1 (18614.2.1.1.1) on macOS Ventura Beta on MacBook Pro 13" M1. I can reproduce on Safari STP 151 Version 16.0 (17615.1.1.2) on macOS Monterey on MacBook Pro 13" Intel On a profile it seems to constantly reload this resource and time to time a couple of CSS. https://fast.fonts.net/t/1.css?apiType=css&projectid=cb6b236d-f129-416d-8196-4f29ffe0c887 which is happening on MouseMove events being dispatched in https://www.plannedparenthood.org/cdn-cgi/scripts/7d0fa10a/cloudflare-static/rocket-loader.min.js So maybe it has been fixed, a regression bisection could help confirm that. I'm at 16000 fetches and still going on. Tested on PASS: do not reproduce FAIL: reproduce the issue * PASS Safari Version 15.6.1 (17613.3.9.1.16) macOS Monterey - Intel * FAIL Safari TP 151 (17615.1.1.2) macOS Monterey - Intel * FAIL Safari TP 152 (17615.1.2.3) macOS Monterey - Intel * PASS Safari Version 16.1 (18614.2.1.1.1) macOS ventura beta - M1 * PASS Safari TP 152 (18615.1.2.3) macOS ventura beta - M1 (1) (1) Though for Safari TP 152 on Ventura without moving the mouse, and leaving the window Idle, time to time there is a glitch, but nothing on mousemove So that seems hard to bi-sect to find out the culprit. Ahmad, could you describe your device configuration? Alexey, yours too. I'm trying to understand if this happening only on certain OS versions and/or hardware. <link rel="preload" as="style" href="https://fast.fonts.net/cssapi/cb6b236d-f129-416d-8196-4f29ffe0c887.css" /> <script src="/cdn-cgi/scripts/7d0fa10a/cloudflare-static/rocket-loader.min.js" data-cf-settings="c8446d81fabb38acc0204716-|49"></script> <link rel="stylesheet" href="https://fast.fonts.net/cssapi/cb6b236d-f129-416d-8196-4f29ffe0c887.css" media="print" onload="this.media='all'"/> <noscript> <link rel="stylesheet" href="https://fast.fonts.net/cssapi/cb6b236d-f129-416d-8196-4f29ffe0c887.css"> </noscript> And 1.css is being constantly reloaded on mouse move. which is the first line of https://fast.fonts.net/cssapi/cb6b236d-f129-416d-8196-4f29ffe0c887.css with: @import url(/t/1.css?apiType=css&projectid=cb6b236d-f129-416d-8196-4f29ffe0c887); ok The issue seems to stop when I remove ``` onload="this.media='all'"/> ``` with a local override, but is it really the source. Yes it is. If add again the attribute in the local override It will recreate the issue. OK we may have now the source of the issue. What the code is telling us about this? That could be similar to Bug 243123 ok this is a technique which seems to be recommended on stack overflow to load css asynchronously https://stackoverflow.com/questions/32759272/how-to-load-css-asynchronously (In reply to Karl Dubost from comment #6) > Ahmad, could you describe your device configuration? > Alexey, yours too. > > I'm trying to understand if this happening only on certain OS versions > and/or hardware. I am using MacBook Pro M1 Pro with macOS 12.5.1. I couldn't reproduce on a M1 Max 16" MacBook Pro. Also probably media="print" should not be loaded at all. Bug 243424 shows that currently link media print is blocking the rendering when it should not. *** This bug has been marked as a duplicate of bug 244879 *** |
