    I installed razer cortex along with the razer central. However, when I try to open cortex a black screen pops up so I cant login/use it at all. I tried some stuff I found online but nothing worked. upload_2022-12-6_13-7-27.png

    I have been having this issue for almost a month now. No success. Here is how to reproduce the issue
    1. Install Windows on a VM(kvm) without any razer hardware plugged in
    2. Install synapse and start.

    That's it. if you fix this issue synapse will become useful not only for doze users but also for linux users since they can use the VM to configure the macros.

    Very poorly developed/tested application. Base QA should help it work in worst conditions instead of best conditions.

    I get this after rebooting my computer once I've installed Synapse, maybe not the first time I reboot, maybe not the second, but I get it consistently... Reinstalling doesn't always work, but this is the 4th time Synapse has broken like this, and it's really getting on my nerves.

    I'm unable to use any of the features of Synapse 3 or Cortex or anything that require me to be logged in..

    Razer Central v. Razer Synapse v. 3.4.401.32710 Razer Cortex v.

    It is a wild guess, still many applications showed a black on my system lately. Trying to pinpoint the issue, playing with screen settimgs i noticed all applications displayed on my old secondary monitor with no issues. Suspecting a corrupted GPU driver (AMD prereleases are prone to show all kinds of strange behaviour) i did a clean install. Nevertheless the problem perisisted. I could start on a (much too large) window on the old screen and drag it over. Long story short in the end the culprit turned out to be MS auto HDR feature on Win11 which i had to disable manually for affected applications.
