Project Manager doesn't redraw / update correctly as user enters text or navigates between controls.

[pipehat]

Godot version:
3.0.6 (same behavior confirmed with 3.0.[2-6])

OS/device including version:
Windows 10 (Version 10.0.17134 Build 17134)
Intel Graphics HD 515 (Driver 10/1/2018, 25.20.100.6326)
Surface Pro 4

Issue description:
Problem 1) Upon starting godot, project manager splash appears but seems frozen. Moving mouse or pressing key causes it to update to show the project list and buttons.

Problem 2) keyboard input is displayed 1 character behind the last button typed. eg

typed -> visible
a ->
ab -> a
abc -> ab
abc BACKSPACE -> abc
tab to another control -> ab

Steps to reproduce:

1. start godot
2. observe PROBLEM 1 (above): prolonged (20+ seconds) splash screen
3. move mouse or press button to cause splash screen to update to the project manager form
4. press the NEW PROJECT button
5. begin typing text in the project name or path field
   6 observe PROBLEM 2 (above)

Minimal reproduction project:
n/a - happens for me with any project, just start godot

Older Godot version, 2.1.5, works fine.

issue #12509 may be the same as my 'Problem 1' stated here. That issue doesn't mention my 'Problem 2' regarding input delay.

Issue #15953 is definitely related. Has a workaround (start godot with --verbose flag). Sounds like it may be an Intel graphics driver bug.

Closing this on that basis.

This seems to be the same issue as #23069, probably an Intel drivers bug indeed.

I am currently experiencing the same issue with the 32-bit edition on Windows 10, also with an Intel GPU, with Godot_v3.1.1-stable_win32. The --verbose flag does solve the problem, but without it the project manager is effectively unusable. I think that I am using the latest drivers.

I use the stable 3.1.1 64 bit edition on Win 10 with an Intel GPU and the --verbose flag did fix the issue for me.

Win 10, Godot 3.2 Steam edition has the same behavior and is also fixed by using the --verbose flag.
