Red Squares instead of most view icons [message #1836478]

After updating to Eclipse 2020.12 most icons from Views are turned to red squares every time I restart Eclipse (screen 1). They turned back to normal when clicking on them (screen 2) until next restart. Any way to fix it?

How was this update done, and what release are you coming from? You have perspectives that used to be there acting like they're no longer installed.

Thanks for the reply.

Update was done by installing new the version of eclipse into the new folder.

Previous version of eclipse I've used was 2020.06 (4.16).

I know that it looks like so but it is not the case I've shown on the screenshots the behavior: view icon appears when view clicked and that works for all views with red icons but all icons turns red again after eclipse restart. And this bug affects built-in views as well (for example Breakpoints, Variables, Expressions etc. views are affected). I've made a screen collage to show the problem on one image.

I've checked the workspace log files and there are a lot of FileNotFoundException about .gif files, like this:

java.io.FileNotFoundException: /icons/full/eview16/debug_view.gif

So after 3 hours thrown at restoring workspace from backup and reinstalling Eclipse several times I think the problem is that the Eclipse 2020.12 incorrectly upgrades workspace to the new version.

I've managed to fix this by using Export->Preferences in previous version of Eclipse to export my workbench and reseting workbench (delete workspce\.metadata\.plugins\org.eclipse.e4.workbench\workbench.xmi ) and using Import-Preferences to restore workbench from the file in the new version of Eclipse. Now it works as it should.

go to:
Workspace\.metadata\.plugins\org.eclipse.e4.workbench\

and in the file workbench.xmi, change all *.gif -> *.png

Thanks, eran, changing all .gif to .png worked well for me. I had this issue since a few month and was unable to fix it. Very appreciated :-)
For the others with the same problem, here is a sed command to fix it (assuming current directory is the workspace to fix):

sed -i.bkp -e 's/.gif/.png/g' .metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi

Maybe this step should be added to the workspace upgrade step ?

Thanks for posting this!

I thought it was a graphics card issue on my computer causing it.

I did a replacement of *.gif to *.png as noted below, but I did find there were still one or two icons that were red, this was caused by some plugins that still reference gifs.

If you check your workspace/.metadata/.plugins/org.eclipse.ui.workbench/log file you can determine which plugins still are referencing gif files by the file not found messages, and just change those 2 or 3 entires in the workbench.xml back to gifs.

eg.
plugin/org.eclipse.wst.server.ui/icons/cview16/servers_view.gif

The problem appears after upgrading Eclipse and opening an old workspace from an older version.
After digging as to why this happened, I found it is due to this bug fix: [Graphics]Replace gif icons with png files in Eclipse platform projects

The simplest solution is to delete (or rename) the file in the workspace when it is not open in Eclipse: <workspace>/.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
The views will return to their default layout, but will not loose data, e.g. list of breakpoints.

It was known that this change will break old workspaces, according to bug discussions. E.g. here.
