High PC RAM usage after updating from 4.18

Hello RMoli.3,

That's strange indeed. Can you provide us more context info, like which version of Windows do you use ? Is it the first time you launched TouchGFX Designer 4.21.0 ? What happens if you create a project in TouchGFX Designer 4.21.0 from scratch ? Can you send us you log files ? (C:\Users\YOUR_USE_NAME\AppData\Roaming\TouchGFX-4.21.0\TouchGFXDesigner.log)

I have this problem as well, with 4.20. It seems the memory is not released at any point, eventually causing the program to use pagefile and slowing to a halt.

I have also migrated my project from 4.18. I tried to make a small project from scratch and did not experience the issue, although it could be that the amount of memory used by the 2 screens I created is simply not noticeable enough.

Hello RMoli.3,

We are working now for a patch release that will be available very soon in which we will have this issue fixed. I'll keep you updated about this new release, it will happen soon ;)

Hello RMoli.3 and VAnti.1,

We have fixed this issue in the new version :)

I created a simulation project in 4.21.1: 2 screens (550MB of RAM). So far I do not observe any memory usage increase when switching between screens. I use Win10 Business v10.0.19045

Just to clarify. With the patch update it seems that the infinite RAM usage is fixed. However, when changing between complex screens the amount of RAM usage peaks at high amount of RAM (+3GB) and then falls back (I supose it now correctly frees the memory) to a more normal aroun 1GB usage. This peak makes the whole computer (with my setup) not responsive for around +20sec.

With touchFX 4.18 the time between screen swaps is basically none. My current project has a fair amount of screens thus these peaks have a great impact on my productivity and is not and option.

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.

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.
