It has been documented and peer-reviewed countless of times.

No, it's quite simple: change introduced after translation freeze.

There is a difference between getting fixed and getting released. And released in a stable release. And accepted in most distros in current versions. I still run the bleeding edge PPA in kubuntu so I get most of these fixes, but sometimes it gets buggy again and I need to go disabling stuff until it works again (somewhat)

whoops, the option is ignored for all Intel hardware.
there's no longer a big performance gain from being able to disable KDE's desktop effects when running fullscreen windows/games, at least for Intel's open-source driver with Core i7 Haswell hardware.

Originally posted by smitty3268 View PostIt's not clear that it hasn't been fixed.
The first bug from a couple years ago looks like it was. There may be another problem present only in the i915g driver, which Intel doesn't support (they have a classic driver instead) but it's not clear whether that is still currently present or not.
That bug mentioned by one user was specific to i915 as you say so was never looked at upstream:
Obviously disabling a feature on all Intel drivers because of a possible bug in one unsupported driver reported by one user is a bit extreme, a point that is made by some users in the KDE bug report.

Shift+alt+f12 Worked for me AMD catalyst drivers. hd 5750
After some time I changed the settings of kde.
Turning about everything off, in the settings.
KDE knows about these problems for a while, so they might have fixed it.
I remember a question, why "we" would want to run programs full screen, on this forum by somebody who matters kde wise.
(not recently though)
