[UMG] Tooltips and Context menus in Widgets cause screen flicker in HTML5

Branch: Binary Release (But packaged from source code build of UFE)
Build version: 4.4.0-2255576

I add a simple text box to the UI through UMG, in the Blueprint first person template, and write a tooltip for that text box. When I build this test game for HTML5 and run it in , the screen (i.e. the game screen) starts flickering black rapidly as soon as I put the cursor over the text box. If I remove the tooltip, it works fine, but when I right click in the text box the same thing happens.

This is all I’ve got set up:

Adding the widget to the viewport in the level blueprint:

The simple widget blueprint:

It isn’t completely essential that I have tooltips, and I can disable right mouse input, but this seems to be a bug regardless or is it just me?

ToolTips and other things that create new windows in slate are probably having a negative impact. It will likely be corrected once we automatically turn them into overlay data instead of new windows.

Hmm… I also experience massive lag when testing UMG graphs with elements that have tooltips; This is sad, I’ll have to remove them all.

Hey

Could you please provide me additional information regarding the trouble you’re experiencing? Which version of the Editor are you in? Are you using a lot of ToolTips and things of that nature within your UMG? Are you also packaging and running your project in HTML5? When you’re running your project, what web browser are you using? Please provide as much information as possible.

Update:
I’ve had an update after speaking with the Developers. We’ve included a feature in 4.8 which allows the ToolTips to be added without adding additional windows, this should help any lagging issues that you’re currently experiencing. I’m not sure whether or not it’s coming out in the initial release of 4.8, or a patch later on but it will be implemented in the near future.

Thank you! :slight_smile:
