Windows 7, 64 bit, Quadro FX 4000
Worked: 2.7 and previous
Short description of error
Not so much an issue however, it does annoying to see render glitch.
Exact steps for others to reproduce the error
I have separate window for Render View, so when I click Render, window will pop up.
I work in Cycles last night and with GPU enabled. Saved the file, reopen the blend with Render View active, the issue starts to appear here. Occassionally there is a glitchy windows just like scrambled pixels on top of Render View.
Hopefully it's not my graphic card dying.
