Hi,

I have observed sporadic issues with string length caching with one of our application.
Every now and then (weeks or even months), RAP's string length cache seems to become corrupt - some users with specific Browser+OS+Font combination get completly garbled layout.
E.g. as shown in the screenshot, this time I get distorted layout with firefox but with chrome everything is ok. firefox on windows and chrome are also ok, but with IE11 other components look broken. After restarting the app server, everything is fine again.

I haven't found a way to trigger this in a reliable way, therefore I wasn't able to search for the cause.

However I wonder, are there any ideas what could cause such issues?
Could it be that high-dpi displays are confusing the string cache? Or could it be the startup checks identify a browser belonging to a wrong "group"?

Thanks, Clemens

Hi,

text size determination is not coupled with the browser. RAP assumes that a combination of string, font, style is rendered in the same way in all browsers. One guess is that the user is using browser zoom feature. You could check this.

Regards,
Ivan
