The Bugbug bot thinks this bug should belong to the 'Core::Layout: Text and Fonts' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

It actually flashes across any page that is displayed. It's just more visible on a blank page. It only flashes for one windows message cycle.
It took many attempts to screen shot it.

This doesn't look like a Layout: Text bug; more likely to be a graphics (webrender?) glitch of some kind. Moving to Graphics for triage. (Or might it be Widget: Win32?)

How long has this been happening? Like one day? One week? one month? One year?

How about this? We have a tool called Mozregression which is really useful for Bugs that are easily reproducible. Would you please follow the instructions here, and it should give you a URL of a regression range of possible code landings that caused this behavior?

Meanwhile I'll see if I can reproduce on my Windows system.

Have tried to reproduce without success. Marking as STALLED until we can find someone who can reproduce and run a mozregression.

A couple of things that you could try to help us narrow down the cause:

• Your GPU driver version is from 2023 - is it possible to update this to a more recent driver?
• You have multiple monitors attached - could you remove one of the monitors and check if you're able to repro in that case?

Since the bug is closed, the stalled keyword is now meaningless.
