Description John Sawyer 2009-01-27 15:26:11 UTC
Version:           4.1.96 (using KDE 4.1.96)
OS:                MS Windows
Installed from:    MS Windows

I use Vista x32 SP1 with 1920x1200 resolution. I use 120DPI scaling.

If I start plasma.exe normally, it doesn't detect that I use 120DPI scaling and windows scales the pixels --> resulting if a fuzzy picture.

If I try to correct this, by right clicking plasma.exe property and under compatibility tab selecting "Disable display scaling on high DPI settings", the plasma application doesn't fill the full screen. Instead it is positioned in upper left corner filling approximately three quarters of the screen filled.

I guess the problem is that none of the Windows KDE applications are high DPI aware and they get wrong screen resolution information.

Plasma.exe also somehow affects other running Windows Vista applications, so that in their full screen they are running a bit less in than full screen.

plasma-desktop is not currently supported on MS Windows, though maybe the kde windows team can have a look at this.

I don't know what you mean by "plasma-desktop is not currently supported on MS Windows".

All you have to do is to use high DPI aware "getScreeSize" instead of non high dpi aware in plasma.exe code.

i mean "it isn't supported". it's something people in the kde windows platform team have been working on, but not something that the plasma team provides technical support for at this time. that may change in the future, but that is neither a given at this point nor the current status.

Hello! Plasma 4 was replaced by Plasma 5 four years ago by the KDE community. In that time we have made great strides in stability and functionality. We are closing all Plasma 4 bugs as most of them are no longer applicable to the new frameworks Plasma 5 is built upon. If you could, please re-test with the latest version of Plasma 5, and submit a new bug to "plasmashell" if you continue to have an issue. Thank you!
