What steps will reproduce the problem?

(1) Go to https://m.ok.ru

What is the expected result?

Text on the page is rendered correctly.

What happens instead?

Some text elements are broken, see the "screen_broken.png" attachment.
Also some of the images are broken in the same way.

When gpu rasterization is disabled in about:flags, the problem is not reproduced, see the "screen_normal.png" attachment.

This problem also affects Chrome versions: 60.0.3112.43 beta, 58.0.3029.83

Problems Detected
ARM driver doesn't like uploading lots of buffer data constantly
Applied Workarounds: use_client_side_arrays_for_stream_buffers
The Mali-Txxx driver does not guarantee flush ordering: 154715, 10068, 269829, 294779, 285292
Applied Workarounds: use_virtualized_gl_contexts
Clear uniforms before first program use on all platforms: 124764, 349137
Applied Workarounds: clear_uniforms_before_first_program_use
Always rewrite vec/mat constructors to be consistent: 398694
Applied Workarounds: scalarize_vec_and_mat_constructor_args
CHROMIUM_copy_texture is slow on Mali pre-Lollipop: 498443
Applied Workarounds: max_copy_texture_chromium_size_262144
Limit max texure size to 4096 on all of Android
Applied Workarounds: max_texture_size_limit_4096
Limited enabling of Chromium GL_INTEL_framebuffer_CMAA: 535198
Applied Workarounds: disable_framebuffer_cmaa
Frequent hang in glClear on old android versions on Mali-T7xx: 638691
Applied Workarounds: gl_clear_broken
Disable KHR_blend_equation_advanced until cc shaders are updated: 661715
Raster is using a single thread.
Disabled Features: multiple_raster_threads
Native GpuMemoryBuffers have been disabled, either via about:flags or command line.
Disabled Features: native_gpu_memory_buffers
