Anyone ever see text shimmering / shaking on a web page while scrolling in Edge? It's very temperamental: once you scroll up and down, the shimmering stops. I thought it was my eyes, so I asked someone else and they saw it, too!
Very difficult bug to reproduce; I'll try to record a video next time (or a screen recording, perhaps). This issue does not happen in Firefox 66 or Chrome 76.
Using Edge Version 184.108.40.206 (Official build) dev (64-bit) on Windows 10 Pro x64 17134.765 (1803). Hardware: ASUS VG248QE 24" monitor + NVIDIA GT 710 (430.64 drivers) + DVI-D, at 1920x1080@120Hz Lightboost at 100% Windows scaling and 125% Edge Zoom. Cleartype is on.

@v-gapart Hello and thank you for following up.
did see it once in the previous Dev build (based on Chromium 76) whose version number is eluding me, but since then, I've not seen it again.
However, it is quite rare (one website from perhaps thousands in a week; the last time was on Dell.com on a purchase configurator).
I'll surely update the next time it appears, if ever.

@v-gapart Speak of the devil, I just got the issue again.
1) Occurs on any website seemingly
2) Reproduced on two systems (one laptop, one desktop: both use the same Edge & Windows builds)
2) Scrolling that tab will stop the shimmering
3) Only some text is affected, perhaps only <p> paragraph? Images on the page do no shimmer nor do buttons or other text.
4) As long as the text is shimmering, Edge has high CPU & GPU usage (both pegged at 25% to 30%, even though it's just rendering two simple text-only tabs)
Microsoft Windows 10 Pro x64 1803 (Build 17134.885)
Microsoft Edge Version 220.127.116.11 (Official build) dev (64-bit)
This is the latest Windows for this branch, but not 1903 yet.

@v-gapart I can confirm the bug has reappeared on another dev build, at the same URL.
Windows 10 Pro x64 1803 (17134.885)
Microsoft Chromium Edge Version 18.104.22.168 (Official build) dev (64-bit)

Have you tried turning off hardware acceleration? bad/outdated graphic card drivers or no graphic card drivers at all can cause that. also check edge://flags see if you accidentally enabled any flags related to the rendering.
I also suspect that 120Hrz refresh rate. can you check see if the same issue happens when you run at 60Hrz? maybe there is a conflict in V-sync and screen refresh rate. a video footage would really help.

@HotCakeX Thank you for the reply. Let's clear up a few things....
V-Sync is not being forced by me. If anything, Edge would control V-Sync, not the user. But...this bug doesn't seem to be a V-Sync / refresh rate bug because it only affects certain text on a website. V-sync / refresh rate...would affect the entire website.
Unless you have a different hypothesis?
Please do view the video footage above, @HotCakeX . I think you might be onto something, but hopefully I've cleared up any misconceptions.
I'll try turning off hardware acceleration!
Happy to help share more :)
