Problem: Xorg CPU use 100%

Good afternoon!
Guys, real problem.
Hardware: Nvidia NVS810 8-way miniDP out.
We use xubuntu 18.04.3 and we need to show on every display video. When we add third video xorg use 100% of 1 cpu stream and everything start freezing.
Use drivers 430 from repository.
Try to use xubuntu 16.04, 18.04, various kernels. Result always one. Please, maybe somebody help me. Really don’t know what to do.

What kind of player are you using, with gpu decoding?
Please run as root and attach the resulting .gz file to your post. Hovering the mouse over an existing post of yours will reveal a paperclip icon.

generix, thank for your quick reaction! We simply display input with gstreamer xvimgasink. When the window is one, everything is ok. But if we add one more xorg use cpu 100% on one thread.
Ok, will run and attach collected info

Xv isn’t really widely used anymore, I don’t actually know if this is even still actively supported. You should rather look into gl output.
