After reboot missing taskbar, icons, textures in general

Hi,
im running dualboot on old macbook pro (2013 or smthing). Installed Manjaro yesterday, but in the evening after reboot, all textures went missing. Taskbar just plain white, no icons throughout whole system. I could still click on menus, start buttons and everything - it was just invisible. I tried to find some help online, unfortunately i wasnt successful and so i reinstalled whole os in the morning. However, after I followed a tutorial on gestures, where at one point I rebooted after installing libinput gestures, everything is gone ahead.

Im new to manjaro (used debian a bit before), so any help is deeply appreciated. Will provide any further info upon request. Thanks
