Two quicktiled windows.

If I have two quicktiled windows side-by-side, and I maximize one of them and quicktile it back to where it was before, the other window remains partially covered by the maximized texture. It won't go away until I bring the corrupted window into focus, and then everything is normal again.

Unfortunately when I try to take a screenshot with spectacle, the corruption goes away, so I had to take some pictures with my phone.

I can't remember exactly when this started happening, but I think it was with Plasma 5.11. It happens under both OpenGL and XRender.

System info:
Arch Linux
Nvidia proprietary driver 387.34-21
Plasma 5.11.5
Frameworks 4.42.0
Qt 5.10.0

most likely this is a problem in combination with the nvidia driver.

This bug no longer happens since bug 376104 was fixed.
