System Information
Windows 7, Nvidia Geforce GT 440
also tested official 2.77 on Linux 64 Bit

Blender Version
Broken: 2.77 22a2853
Worked: (optional) 2.76 48f7dd6

Short description of error
When Subsurf modifier is active, while weight painting, you can't select any vertex after pressing 'V'
Instead, the screen darkens( on 'Window Drawing Method' set to 'Triple Buffering') or glitches a bit until next possible window refresh(either 1 second of wait, or mouse move)

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

Open new file
Add 'Subsurf' modifier to a model
Enter 'Weight Paint' mode
Press 'V' to enter 'Vertex Selection masking' mode
Try to select one or more vertices (by right clicking, Circle selecting or Box Selecting)

Can't redo this error.
Please include a blend file in the non-working state.

weightmaskfail.blend

Trying to for example deselect the vertices with B + MMB causes the interface to go dark and weird.

Trying to select vertices with RMB after pressing A to deselect doesn't work.

Edit I record video of it happening

circle/box select does not seem to work definitely in weight paint for the mesh object with subserf modifier.
(vertex masking mode)
