Flickering/screen tearing occurs when using desktop environments other than lightweight ones (LXDE, Xfce vs Unity, KDE Plasma)

I installed a new graphics card 1 month ago (Radeon 1050TI series, AGP, 512MB) while I had Xubuntu installed. I installed Unity to test its 3D performance. It's great! I couldn't ask for any more!
However, I only have one issue; the screen flickers on non-lightweight desktop environments (Unity, KDE Plasma, Gnome 3, Cinnamon), unlike on lightweight ones (Xfce, LXDE).
Let me describe what's going on: Xfce & LXDE work fine, with absolutely no flickering. Other desktop environments, on the other hand, kind of flicker.
- Unity: It flashes the screen about 3 times during logon and while opening Settings (the screen goes black and restores back to working in about half a second)
- KDE Plasma, Gnome, Cinammon: When I hover my mouse over elements (e.g. Kickstarter menu button), it flickers for some fractions of a second and then goes back to original. That element is kind of covered by some strange black shapes. (I think that this is called screen tearing.) Something like this:
Windows, however, installed its own drivers for the card, found it with the 1st try and I now got Aero! And it doesn't flicker!
Does someone have any suggestions as to why some desktop environments flicker but others & Windows don't? I'm open to any ideas.
