I tried to reproduce, but I didn't exactly understand your case. Can you please post your qxw file, and a step-by-step process to reproduce the problem?
Also, please post your platform (linux/windows/osx/raspberry/...) and QLC+ version.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Here is my .qxw file, There are several problems in my file.
On: OSX(64 bit), Ubuntu 14.04 (32 bit) and Windows 7 (32 bit)
QLCplus version 4.6 to 4.8.1
-Saving of rgb panel, text chaser becomes only single line after restart of qlcplus.
-To many data to rgb paneel hangs qlcplus, try enable all four column and line.
-Try to dim the rgb paneel with the submaster, after every change of the panel the intensity resets.

This is indeed SLOW. I've profiled things a little bit to look for speed issues.
For developpers:
I think I managed to speed up things a little bit by switching containers in Scene, still some way to go though.
Attached are two gprof results, before and after the switch.
The test was the same for both the results: run qlcplus, load Rob's workspace, run the 8 chasers for 5 minutes.
Submaster behavior.
The submaster button dimms my led panel but with every refresh the dim setting resets to master level.
see attached video for my home build shiny led screen:

Here are the changes I've made: https://github.com/plugz/qlcplus/commit/5e90aad25eb9c2dcc10d877114f5d394efa75630
also, a question: is it slow like this when you don't transform your rgbmatrices into chasers ?

About the performance issue, if you compile qlc from source, can you test this branch ? Thanks !
https://github.com/mcallegari/qlcplus/pull/368
Try to compile on ubuntu but keep getting errors on the fftw_malloc, fftw_free, fftw_execute, fftw_plan_dft_r2c_id and fftw_destroy_plan libs.
Have you installed all the dependencies, as specified here https://github.com/mcallegari/qlcplus/wiki/Linux-build-Qt5 ?
Problem solved ;)
Compiled and up and running.
Again Problem Solved! before cpu 100% + and hanging. Now around 70% cpu.
Submaster level problem remains.
Yes, I have the same issue.
As a workaround, can you use only RGBMatrices, and not converting them into chasers ?
