[English]There seems that Microsoft Chromium Edge has a bug for some time now that suddenly turns the browser window black. The bug does not affect all users and occurs sporadically. Microsoft has already released a fix in newer betas, but it does not solve the problem for all users. But the fix at least brings improvement.

The bug is confirmed by Microsoft
Some users complain about the strange behavior of the Chromium Edge, which causes the display window to turn black – making it impossible to work. But in the Techcommunity announcement for the Edge beta version 82.0.439.1 you can find the hint:
After an initial fix for it recently, some users are still experiencing Edge windows becoming all black. UI popups like menus are not affected and opening the Browser Task Manager (keyboard shortcut is shift + esc) and killing the GPU process usually fixes it. Note that this only appears to affect users with certain hardware.
There Microsoft confirms the issue, which is probably caused by the graphics unit (GPU). This problem is listed as a know issue, although Microsoft had already rolled out a bug fix there. The fix don't work for all users, but it brings improvements. Without the fix users have to restart the browser or Windows (see this post). But this post pointed out, that the fix brings an improvement. It's now possible to invoke the browser's taskmanager pressing Shift+ESC. Then it's possible to kill the GPU process to enable the browser to render again.
Here's a solution to the problem :
