I've made an example, but it wasn't possible to test it on IE11 because the page of codesanbox doesn't load on this browser. I'm not sure if this example reproduces the problem.
The steps to reproduce the bug can be found in this ticket.
The ClayModal shouldn't be blinking.
| Tech | Version |
| ----- | ------- |
| ClayModal | v3.7.2 |
| ClayTooltip | v3.3.5 |
| React | v16.12.0 |
Hey @naraandrade apparently doesn't seem like a problem with Clay, I modified the demo to get closer to the codesandbox example in the Storybook but I couldn't reproduce it.
Win 10

Thanks, @matuzalemsteles. I'll continue to investigate the problem... We are using the same component structure on another page that works fine on IE11, the only difference is that it's not wrapped by a modal. If you have any suggestions, I would appreciate if you share it. Thanks again :)

@naraandrade I did some tests to try to reproduce this but was unable to get to the modal blink, an assumption would be to investigate if it is causing some type of extra rendering in Modal or who controls it or this blink might be related to some CSS.
@matuzalemsteles Apparently, it's an issue with the "center" prop passed to the ClayModal. When I removed it, the modal stopped to blink.
@naraandrade I'm going to take a look at this again on Monday, thanks for bringing this.
Hey @naraandrade, I still can't reproduce inside the Storybook using the center property enabled but I can reproduce only within the DXP, in the case of the ticket. Apparently, it could be a problem with repaint that is taking too long and causing the blink. I'm not sure why this happens only with the center I will try to continue investigating because it only happens in DXP. @pat270 could you take a look at this when you have time? I'm unable to collect much but if you provide anything information would be very welcome.
