50% Grey Screen problem in 4.5.6 (Win 11 Pro)

[gavhall]

Hi,

I’m seeing the well-documented 50% Grey Screen problem on 4.5.6 (Windows 11 Pro). I had 4.2.2 installed when my system was Win 10 64 but uninstalled it some months ago. I had the same problem then and reported it:

50% Grey Screen problem in 4.2.2 (Win 10 64)

Hi, I’m seeing the well documented 50% Grey Screen problem on 4.2.2 (Windows). Switching the workspace did address this issue as a workaround. I don’t see it mentioned for this version so logging this post. Gav.

I upgraded my system to Win 11 Pro and have just reinstalled KNIME (so used the default workspace) and have the same problem.

Like the last time this occurred, I switched to a new workspace (well the second one I created last time) and the problem resolved itself again.

Thanks,

Gav.

Hello @gavhall

Thank you so much for pointing this problem out. After checking internally, it appears that this bug was fixed in version 4.3.2 (AP - 16147). This issue happens when workspace gets corrupted. Ideally, like you mentioned, switching the workspace fixes the issue. However, if possible please try the following with your old workspace:

• Add a -clearPersistedState command on the top, in your knime.ini file. This file is located in the installation directory of KNIME. For instance C:\Program Files\KNIME is my installation directory.

• If above doesn’t work, you can try deleting this file in your workspace directory:
  .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi.

Thanks!

Can't maximize window

Hi, new KNIME and have installed it on my system. I have this weird issue going on the program where I can’t seem to maximize any windows. It is only using half of the window space no matter what the size of the program window. I have tried the reset perspective and even uninstall and reinstall but no luck. [Capture2] I am using Windows 10. thanks in advance

Grey area in workflow editor

Hi folks. I know this topic has been covered before (Grey Area in Knime Workflow Editor) but I am seeing the same issue and wonder if there are new developments / priorities in troubleshooting. OS is Windows 10 Home v 1903 and Knime 4.2.1 (problem occurs identically with laptop and auxiliary VGA monitor).

Half screen problem (50% grey)

I’ve seen and tried to apply the recommended solution for the Windows / Half Screen bug using version 4.2.3, (which is to change workspace i believe)… but the fixes listed haven’t helped. Any other ideas? [image]

P.S: There is no 4.5.6 KNIME version
