How to prevent the blueprint suggestion window not showing bug

If you use the Unreal Editor for a little longer, there are symptoms that the blue print proposal window becomes transparent and invisible.
Despite it is not visible but It works, so if you click where the place of empty space with your mouse or type the Enter key, it will be selected correctly.
In order to solve this problem, I have to shut down the editor completely and run it again, so is there an easier solution?

Hey there @LikeThatAng! I’ve seen this bug on older UE versions but not as recent as 4.27. Has this only occurred over time, like say when the editor is in full use the whole time, or are there lulls, sleeps, and wakes that the editor has to go through before this occurs?

Also if possible, I can check your specs up against a couple from previous threads to see if there’s a pattern for the report.

Thanks in advance!

The problem occurs over time, it’s just popping up suddenly as it works well right before.
It is difficult to assume specific conditions that cause the problem.

Below is a simple specification of my working computer.

Thanks! I’m going to attempt to replicate this by running UE4 in the background on my secondary PC while I’m working. The version is 4.27 as the post shows correct?

Yes. My UE version is exactly 4.27.2.

It may be a nvidia issue, a friend solved it thanks to this :
