    so, every time I open up Unity in the 2020 editions, this happens:

    upload_2021-1-21_10-53-57.png

    Everything gets messed up. I can't press anything properly without another menu above dropping down (not the one I was selecting). It also seems that the menus stack on top of each other. The UI is also smaller than the original window size. I cannot click anything else (besides the dropdown menus).

    When I use the 2019 versions the Package Manager is completely blank.

    Is there any way to fix this?

    This is very likely caused by a bug with intel integrated gpu drivers. Downgrade them below 27.20.100.9030 or use OpenGL/Vulkan. We are currently working on a workaround which will be backported as far as necessary.

    I can confirm that. Had similar issues for some weeks now. Then I saw this post today and remembered that some time ago I have upgraded my integrated Intel gpu drivers. Performed a rollback and this fixed the issue.

    Before that I have tried different things (firewall, anti-virus e.g.) and different Unity versions and nothing helped. In the process I noticed the following:
    1. Unity 2018.4.31f1 (LTS) was working without problems
    2. Unity 2019.4.18f1 (LTS) some of the windows were empty but when you moved the mouse around the window the cursor changed as it there were some invisible UI elements
    3. Unity 2020 (a few versions that I have tried out) UI elements were visible but the layout was off and some fields were empty were there should be some package info, which on the other hand was perfectly visible in inspector.

    UIToolkit is particularly affected by this issue. It didn't show up with 2018.4 because the renderer was different. The new renderer stores clipping and transform data in a texture. This driver bug causes the GPU to occasionally sample 0.8 instead of 1.0. This causes the UI to be incorrectly scaled, clipped and masked (e.g. depth tests that must fail don't fail anymore). Also, since more and more editor content is done with UIToolkit with each release, there is more exposure to this issue in the latest versions. We will backport a patch down to 2019.4.

    Any ETA on when the patch may be backported to 2019.4?

    It's likely to land in 2019.4.21f1, so by the end of the month.

    2020.1 is part of the tech stream and its support period is over since 2020.2 has been released. The fix should land in all affected versions of the editor (that are still supported) before the end of the month.

    If you are badly affected by the issue, don't forget that you can downgrade your drivers below 27.20.100.9030 or use OpenGL/Vulkan.

    @pccross FYI our patch has landed in the code base of the affected branches. It will be part of the following versions of Unity:
    2020.2.5f1 by Feb 21th
    2019.4.21f1 by Feb 28th

    Of course those are estimates and subject to change if something goes wrong with our release process.

    Hey there Alex! I'm facing the same issue as everyone here, I'm on unity version 2019.4.20f1 and my package manager tab is showing in blank/empty, I've tried anything (updating driver, turning off anti-virus..) and nothing worked

    you said that the newer versions of unity had patched this issue so i was wondering which version is better and had the issue solved?

    it's july 2021 and the version (LTS) available are : 2019.4.28f1 / 2019.4.36f1 / 2020.3.15f1

    is the issue fixed in all these versions? and which one should I go for?

    Hi @aym23B, the issue should be fixed in all these versions, but you could also simply update your drivers.
    Intel has fixed the driver issue in 27.20.100.9466+
