Burning Crusade Alt tabbing / Switching between clients buggy AF

[Nekta]

Hello I recently updated my Windows, after i did this alt tabbing between clients or even between desktop and the wow client has become very buggy.
When I alt tab out of wow and then go back it will crash for like 20 - 30 seconds and then open the client normally.
Is anyone else experiencing this problem and does anyone know a fix.
Its not like a killer bug but its annoying AF to have to wait 30 secs every time i reopen wow.

I will reward 100G to the person that can point me towards a fix for this lel.

Tinker around with your graphics drivers and or the application it uses to modify settings (nvidia = nvidia control panel) I had the same problem, but with a vanilla client and downloading some driver combined with a reboot fixed the window bugs I had.

If I'm missing out on what you mean (are you using windowed mode?) - this could very much be so simpler if not. If you've got a game on fullscreen, doing anything else on a second monitor (clicking, or just alt tabbing to remove that game from the monitor to do other activites) will most likely do exactly what you're describing.

I do not use windowed mode and have 1 screen.
Ill try some things whit my driver i guess.

You'll need to use windowed mode to avoid any blackouts and any of the problems that come with the deficiency of being fullscreened.

Use windowed mode and you'll have no problems.

No worries, this will also count for anything in the future too.
