Wondering if there is a solution to this problem

Its really hard to work with the basic theme

I had the same issue. I created an account to say that the above fix worked with a similar PC build: using windows 7 and a 980. Rolled back to Nvidia 368.81 driver.

After doing some research on reddit and blender artists the problem seems to be with the lastest Nvida version

Which fits with the timeline of when blender started to mess up

Simple fix:

  • Roll back to version 368.81 or early to fix the problem

Hope this helps other people

Albeit this is more of an OS and a hardware question and the overall lack of information regarding your system, let's try it anyway.

Windows turns off Aero for two reasons. Either it "feels" that it could save system resources due to weak hardware or heavy load by turning it off or you are running Blender in compatibility mode.

Random Deactivation:

Windows Aero is a so-called compositing window manager and therefore relies on 3d acceleration itself. Random deactivation happens quite often when you are running games or Software that depends heavily on 3D acceleration, but sometimes it also happens randomly (e.g. Windows decides what's best for you).

One reason for this is the overall temperature of your system and mainly your GPU. It's a common problem during the summer months but it also might be a hardware-related problem (e.g. dust in the fan/heat sink, bad fan, defective fan, low fan speed due to bad user settings...).

Unfortunately there is no "magic switch" to prevent Windows from the fallback. All known registry settings solve this "problem" only temporarily. There are some tools that ease the process to reactivate Aero, like Aero Switcher, but I can't recommend any since I do not know which windows version you are running.

Compatibility Mode:

Right-click on your Blender Icon, select "Properties" (again - I don't know your windows version) and check the "Compatibility" Tab. There might be an option called "Deactivate visual Designs" or something similar.

If Blender runs in any other mode than the one that is native (your windows version), switch the settings to your windows version.

Try this: Right click on the blender shortcut then select properties then go to compatibility and uncheck Disable desktop composition and unckeck Disable visual themes. Hit apply and then ok. Hope this helps.
