Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

[UMG] Choppy text scaling bug in 4.21.2?

Simple text scaling up and down UMG animation in 4.21.2. Was completely smooth in 4.17, what could be done?

(FPS rate, Font doesn't change anything, able to reproduce in a new project.)

Text is also way more jiggly in 4.21.2 when being dynamically scaled up/down in a widget using Widget Transform.

Someone reproduced the issue and observed that it's scaling X and only in the next frame scaling Y, hence the choppy appearance. As a workaround, was advised to change render scale from blueprint but I'd like to know whether my method can still be used or if there could be an engine bug.

Many thanks in advance!

Please find attached gif.

Product Version: UE 4.21

Thanks for the suggestion, but I mentioned in the description that any FPS rate doesn't change anything for this. Text X and Y values also don't scale simultaneously when using Widget Transform and other methods.

Sorry, my bad. I missed that somehow.
