Describe the bug Colour Shift on Universe Change using cross-universe feature See: https://www.qlcplus.org/forum/viewtopic.php?p=76779#p76779

To Reproduce Steps to reproduce the behavior:

1. Create an RGB Panel with 30 columns x 10 rows
2. Mark Allow Cross-universe
3. Components RGB
4. All other options as default
5. Click OK
6. Go to Function Manager and create a new RGB Matrix, solid color Red
7. Test the new RGB Matrix
8. The first universe pixels lite in Red
9. The second universe pixels are Green

Expected behavior The pixels of the two universes must be turned on in red. For RGB LED strips use a maximum of 510 channels per universe. For RGBW LED strips it is correct to use 512 channels per universe.

Desktop (please complete the following information):

• OS: Ubuntu 24.04
• QLC+ 4.14.1-GIT
• Enttec Octo MK2
• RGB Led strip

Additional context It seems that Enttec Led controllers (maybe other brands too) on universe change when using a RGB led strip are not using channels 511 and 512. Universe split to next universe occurs after channel 510. It allow to use 170 RGB pixels per universe.
