Applications won't minimise and on clicking or attempting to drag, it doesn't show any response. Rather, the desktop background appears in small rectangular blocks. - Though, soon when I tried killing the running applications with patience, the KWin bug report came switching off the desktop

You experiences are mostly (please don't collect issues into a "complainments" bug report - makes them hard to deal) outcomes of the fullscreen unredirection (tooltips break the fullscreen, thus unredirection - that it only occurs on a fullscreen window would have been a valuable information, btw. I just randomly can say it from the backtrace since that's a known intel bug) crashtrace is a driver bug, to workaround either really suspend compositing before going fullscreen (shift+alt+f12) or disable suspension for fullscreen window (yes, sounds weird ;-) in "kcmshell4 kwincompositing" (3rd tab) you might want to elaborate on the "won't minimize" issue - you mean from the taskbar? Do they minimize using the minimize button? *** This bug has been marked as a duplicate of bug 252817 ***
I'm not sure how you that fullscreen caused. I rarely switch to fullscreen. I was going through the bug marked as duplicate of mine, so just to clarify I'm also not multiple screen. Whenever it crashes the unusual behavior is that it stops responding to any input and I get to see rectangular patches. For example, if I'm on a text editor UI or firefox, suddenly things will freeze and on any input(even the movement of mouse) would cause formation of blocks making the desktop background visible. That is I partly see firefox window and partly desktop. Regarding minimize, if I try to minimize firefox window, it won't do that or even if it does, pieces of the firefox window would still remain on the screen. This all happen due to desktop effect or the supporting driver for the hardware or you said, Intel. As soon as the bug report could be found, desktop effect was automatically turned off and it came back to normal.

Er, sorry, for typing mistakes in there
The backtrace on *this* bug is the same as on the dupe. It usually occurs when a window drops out of unredirection on the intel driver. The amount of screens is rather unrelated to that issue. -> i concluded that some client dropped out of unredirection (would explain "flicker" when eg. toolips or popups appear) and this happens on fullscreen windows only (ideally...) "pieces of the firefox window would still remain on the screen" - that's purely visual. If this is while compositing, there's sth. heavily broken (framebuffer - intel tries flipping but can't?, damage events) - I assume it does not happen if you use XRender ("kcmshell4 kwincompositing", 3rd tab). - Do you use blurring and is it related? (2nd tab) - What kind of GPU do you have? (in doubt, attach a dump of "glxinfo > myglx.info"

There's nothing attached - you're mailing to a bugtracker. (For the same reason you don't have to keep quotes. It's all stored anyway) Go to the webpage and "Add an attachment" with the link on the very bottom of the posts. What do you mean by "Its as if no desktop effect is enabled" - you can't even make windows translucent??

Yes, I can see windows translucent on dragging them. Its partially enabled.
