High PC RAM usage after updating from 4.18

[RMoli.3]

I am trying to update from 4.18 to 4.21 to use the new features of the 4.21 release. I find myself unable to use the 4.21 touchgfx designer due to infinte high RAM usage.

• With 4.18 touchgfx my project uses around 700MB and raises to 900MB when switching trought the screens.
• With 4.21, toucghfx my project uses around 1GB and raises around +1GB everytime I switch between the screens. This means that after switching a couple times of selected screen it is already using +7GB of RAM. The RAM usage keeps increasing until it crashes.

Has anyone experienced this behaviour?

I am using a STM32F7676

I have the same experience as RMoli.3, with the difference that whereas previously with 4.20 the screen was eventually changed (after ~30 seconds of the program not responding), with 4.21.1 it simply never happens (at least not in the 10 minutes I waited). So with my setup the new version is no longer usable.

At least in my case, I think the culprit is the Text resources. I have over 200 texts with translations to 6 languages, and if I remove the texts from the project it works fine.

[MTora.1]

I have same problem too.

it takes a while to cache data to RAM.

Version 4.21.0

Hello RMoli.3 and VAnti.1,

Thanks for reporting it :thumbs_up:

Indeed, it seems like projects which include a lot of text resources makes TouchGFX Designer not responding. We're currently investigating this issue and apparently this is due to loading every resources in the screen canvas. I'll let you know when I have more info about it.
