#1360 TexStudio window disappears when screen is switched version graph

[Ralf]

The TexStudio window disappears when I switch from one screen to another.
To reproduce, you need two screens (in my case, the laptop screen and an external one):

• Enable only screen A
• Open TexStudio, and maximize it (the latter may or may not be critical)
• Change your screen setup to disable screen A, and enable screen B, at once
  (doing two subsequent calls to xrandr will not reproduce the issue).

Now the TexStudio window is gone. Opening TexStudio again in the menu does nothing.
Instead, I have to kill it, losing all unsaved work.

This is pretty bad for the typical laptop usecase of switching between stationary work (with an external screen, and the laptop lid closed) and mobile work (with the internal screen) - every switch of location will break TexStudio.

I am pretty sure that I also saw this bug happening with TexMaker, and was very happy to see it fixed when switching to TexStudio. So much for this...

Version information: Using the Debian testing package.
TeXstudio 2.9.4 (hg 5006:b43062855b2d)
Using Qt Version 5.3.2, compiled with Qt 5.3.2 R

This appears to be a Qt bug: https://bugreports.qt.io/browse/QTBUG-46024

There's nothing we can do about it from within TXS. As a workaround, switch the screens consecutively or compile with Qt4.

Okay, thanks for the pointer. I downgraded to an older Debian package, and hope that not too many applications are moved to Qt5 before this bug is fixed...

[Jan Sundermeyer]

you could also use one of our packages (see webpage). At the moment all linux packages are compiled against qt4.

[bugs:#1324] contains a report that this is fixed (for windows at least) in Qt 5.5
