Flash white screen after 12.1.2021

[#1]

Hello, please help me with the following problem:

After the Flash Player was discontinued on 12.1.2021, my computer keeps going into a white screen with Flash logo. This happens always after a couple of minutes of nonactivity. I have uninstalled the Flash Player using the unistallation program provided by Adobe, it did not help. Then I deleted some Flash Player folders that the uninstallation program had been unable to remove, this had such an effect that the Flash logo on the white screen dissappeared and now the white screen in truly white only. Then I tried re-installing and deleting Flash, but that didn't help either. This is annoing, how can I get rid of this white screen that appears to be caused by the Flash Player?

Right after writing this guestion, I realized that this white screen appears about the same time me screen saver should kick in and behaves similarly to a screen saver (any action or mouse movement causes the white screen to dissappear). After I changed my third party screen saver back to built-in windows screen saver, the problem went a way. So, it turned out the culprit was my "logfire" screen saver.

Problem solved, but I guess it's good that this guestion and solution remains in this forum for others to see.
