is it normal, that the meters in eXT freeze/stop when tweaking knobs (with the mouse) in some vsts? (doesn't happen with all vst plugins)

I've had this happen to me quite a lot of times.

ok. just wanted to know, that i'm not the only one with this behaviour ...

I think this is just a matter of bad programming from
the creators of the VSTi/effects. If you update the
parameters wrong you could end up with a situation
where the update callback gets called all the time
like a feedback loop where the VSTi/effect hijack
interrupt time from other threads...

what functions should the developers of such (bad) plugins better not use to avoid 'freezing host-gui'?

AFAIK this has always been a problem of the VSTGUI library and its implementation of the mouse function (while-loop).

Indeed it is a limitation of the VSTGUI library and a large number of plugins exhibit the same problem

In the days before I got into SynthMaker, and used to write little plugins in C++, I wrote my own GUI lib because of this problem - I couldn't stand it freezing up the hosts GUI!

HeLLo

this thread is OLD and not really in the good zubforum but it's the only one about the subject:

Has the problem with VSTGUI been fixed ?

this has always been a problem of the VSTGUI library and its implementation of the mouse function (while-loop).

i guess the answer is NO. because i downloaded and compiled DRAWTEST and it's still freezing the host when tweaking the mouse.

this make the VSTGUI useless.
