My particular problem is that Reaper DAW hangs/not responding when I try to open VST plugins on second and 3rd displays connected to my computer. They work normally if opened on 1st(main) display
The plugins affected: FabFilter, MeldaProduction, Waves
My system: Win10, Ryzen 3900x, 64Gb RAM, NVME SSD, 1080Ti (3 displays connected), latest drivers
The problem with FabFilter can be solved as descripted here: https://www.fabfilter.com/support/faq/#how-can-i-disable-graphics-acceleration-on-my-computer
The problem with MeldaProduction can be solved by disabling GPU acceleration in plugin settings.
However I found that it is general problem for many VST plugins and different DAWs: they hang or crash when Nvidia graphics card is used and more than 1 display is used. I suppose it is OpenGL related problem, so maybe there is general solution for any VST plugin and any DAW.
