You can make it larger!
Right click the program and go to properties (in windows.) There are some settings in the Compatibility menu. I forgot exactly what I changed but I ended up with a much larger dsp window by messing with some of these https://i.imgur.com/FlRSZWe.png
It is a bit of an issue that you can’t configure this within the software but IMO there is a much bigger issue with the DSP mix on the UR series and the UR824 in particular.
The line outs do not appear to be usable as sends in any DAW other than Cubase. This is Vendor Lock In and it honestly a disgraceful move on Steinbergs part. One that has my interface listed on the market and will have me staying away from, and warning my peers about Steinberg hardware and software in the future unless resolved. If you want to learn more about the issue, read any of the several other users experiencing this issue. I bumped several of their threads and posted my own here https://www.steinberg.net/forums/viewtopic.php?f=157&t=145911.
Hope the Windows trick helped you with your initial issue.
