IE11 Flickering Issue
 

I am running 4.2.5 and just installed the latest patches. Now I am noticing some issues with IE11. For example when on the Quick Reply the cursor will constantly flicker. So as you type characters are missed. There doesn't seem to be any issue on Chrome.

I did some searching and seems there are some flickering issues with IE11 in general and I am wondering if there is some fix for vBulletin to stop this behavior.

Thanks

It's not vBulletin causing it. It's your registry - something's working in the background causing a lot of CPU usage. Go ctrl-alt-delete to get Task manager up, see what's happening with your processor usage.

IE is garbage. Use a different web browser.

Yea I use Chrome, had a user report the issue and tried IE myself and see the same thing. Was hoping there was some fix.

Seems more of a browser related issue than something that can be solved in the code. A website does not have control over the cursor or refresh rate of the cursor when typing.

I always advise people to upgrade to a modern browser. As stated, IE is garbage. :)

I do not have issue with IE, in vb4.2.5, using 5.6.32, 7.0.26 and 7.1.12.
I do not know if IE is a garbage but I must respect users in my forum that use it.

November 2017 in a poll thread in my forum:
IE = 107
Chrome = 82
Firefox = 76
Safari = 9

P.S. I use Firefox and Chrome.

I feel like I am doing users a huge favor by encouraging them to upgrade to a modern standards compliant browser. It greatly improves their browsing experience not only at the sites I help admin, but everywhere else as well. :)

* users that will hear you-me about browsers they most off them will stay to what they use for habit.
* users that know which is better do not need to tell them.
* users that have problem with some browser, will find the way.

All above from my personal experience, does not mean it is the same for others.

P.S. For some reason, some users are prejudice with IE.
Sorry that I am of topic. :)

I certainly am prejudiced, but that's because I know my CSS will likely fail in IE, while it works in all modern browsers. Rather than bloat my code with workarounds for a broken browser, I would rather encourage users to upgrade, and if they refuse, they can live with IE's long list of issues by their own choice. :)

If you check the Task Manager as I suggested, you can determine if something on your site's page is causing high CPU load. Watch the load as you toggle between tabs, or as you open/close the browser window which is displaying your site. This is the only sure way to diagnose if it is something on your site causing this issue.Not directly, but that site COULD be using tons of your processor, causing the cursor to flicker. Seen it before. The OP saying this started immediately after he installed the latest patches gives me some suspicion.

I guess so. A cryptocurrency miner could definitely cause something like this.

Anything that is using a lot of processor will.
