Qt 5.15.4 and upper + nvidia driver 340.108 = Segmentation fault of all Qt soft

Debian Sid.

With nouveau all working good. But after installing legacy 340.108 nvidia driver for my gf9800 i have Segmentation Fault at launching all Qt GUI software. And opposite, Qt works again after uninstalling nvidia driver.

But very strange that if i run Qt soft via debugging tools such gdb or strace i have no errors.

gdb ./qbittorrent
strace ./qbittorrent


Only two Qt application starting normally - CMake GUI and Audacious Qt theme

Is where any solution to fix this? Who can fix this Debian or Qt devs?
