Bug#816993: wmaker: versions > 0.95.6-1.2 break some fullscreen applications (DOSBox, quakeforge, vavoom)

[Matti Hamalainen]

Package: wmaker
Version: 0.95.6-1.2
Severity: normal

Dear Maintainer,

After upgrading wmaker and related libraries to 0.95.7*, various programs
including some (but not all) OpenGL / SDL apps no longer work in fullscreen
mode and sometimes even crash.

The easiest way to check this is to try and switch between fullscreen in DOSBox
(alt+enter).
The result on broken Wmaker is .. weird.

Downgrading wmaker to 0.95.6-1.2 debian package corrects these issues.

Please notice! This issue might very well be hardware (Intel HD Graphics 4600
Haswell / core i7-4770) dependant. At first I suspected the recent Xorg, Mesa
and Intel DDX upgrades, but somehow Wmaker seems to be the culprit ...

I am running a custom kernel, but the issue occurs on stock Debian kernel as
well.
